Given:

The graph of a function f(x).

To find:

The solution set for f(x)>0 and f(x)≤0.

Solution:

From the given graph it is clear that, the function intersect the x-axis at 3 points, i.e., x=-4, -3 and -2.

The graph is above the x-axis before -4 and between -3 and -2.

So, the solution set for f(x)>0 is [tex](-\infty,-4)\cup (-3,-2)[/tex].

The graph is below the x-axis between -4 and -3; and after -2. For f(x)≤0, those values are in the solution set for which f(x)=0, i.e., x-intercepts. So, we use close brackets in the interval notation.

So, solution set for f(x)≤0 is [tex][-4,-3]\cup [-2,\infty)[/tex].

3x + y = 15 What is the solution of this system of equations? (5x+2y=-4

Answers

Answer:

x=34 y=-87 (34,-87)

Step-by-step explanation:

3x+y=15 rewrite to solve for y -----> y=15-3x

5x+2y=-4

Plug y=15-3x into 5x+2y=-4

So, 5x+2 (15-3x)=-4

Distribute: 5x+30-6x=-4

Combine like terms: 30-x=-4

Solve for x -x=-34

Solve for x x=34

Then, to solve for y, plug "x" into 3x+y=15

So, 3(34)+y=15

Distribute: 102+y=15

Solve for y y=-87

A parabola can be drawn given a focus of (-4, -5) and a directrix of y=3. Write the equation of the parabola in any form.

Answers

Answer:

The equation of the parabola is (x + 4)² = -16(y + 1)

Step-by-step explanation:

The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where

The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p

∵ The focus at (-4, -5)

∴ h = -4

∴ k + p = -5 ⇒ (1)

∵ The directrix at y = 3

∴ k - p = 3 ⇒ (2)

→ Add equations (1) and (2) to find k

∴ 2k = -2

→ Divide both sides by 2 to find k

∴ k = -1

→ Substitute it in equation (1) to find p

∵ -1 + p = -5

→ Add both sides by 1

∴ -1 + 1 + p = -5 + 1

∴ p = -4

→ Substitute the values of h, k, and p in the formula above

∵ (x - -4)² = 4(-4)(y - -1)

∴ (x + 4)² = -16(y + 1)

∴ The equation of the parabola is (x + 4)² = -16(y + 1)

Answer:

a) no

b) yes

Step-by-step explanation:

a) You cannot draw the graph around x=0 without lifting your pencil. The function is not continuous at x=0.

b) You can draw the graph around x=1 without lifting your pencil. The function is continuous at x=1.

_____

Additional comment

In technical terms, the limit from the left at x=0 is 2; the limit from the right is 3. These are different, so the function is not continuous there.

On the other hand, the left and right limits at x=1 are the same (both 2), and are equal to the value of the function at that point (f(1)=2). Hence, the function is continuous at x=1.

Gautam My father was not an emotional person. He didn't talk much either. On those rare occasions when he did, he never used more words than what was needed. As a result, I did not benefit from a first-hand account of the Cultural Revolution. Instead, I was forced to gather information from other sources. But that wasn't good enough for me. I wanted to hear it from him. We left our country for America when I was just a child. I never knew if my father had worked in the revolution as a peasant, solider, or a revolutionary intellectual. I tried to picture him writing big-character posters and holding great debates with his fellow revolutionaries. Did he use big words? Did he sometimes skip classes to meet with the comrades across China? These were questions I often asked myself. I wanted to ask him if he believed that the right to air one's views fully really existed in his youth. As an only child, who was brought up to think that education was my only key to prosperity, I didn't know why my father did not finish his degree. My father's friends behaved just like himquiet, laborious, and mysterious. They all looked at me with eyes full of love and hope. Only once, did I hear one of them speak about the past. Uncle Chen recounted something about "not being a Communist," "arrest," and "freedom." It was then that I realized my parents and their friends had always talked to each other in Mandarin, the language I could no longer grasp, when they spoke about their lives back home. At that moment, I regretted my dwindling Chinese vocabulary and the opportunities I had already missed. 9 Based on this excerpt, the Cultural Revolution in China A. provided safety for people who didn't support communism. B. encouraged all citizens to be involved in changing the nation. C. discouraged the citizens from holding meetings and debates. D. demanded that the revolutionaries move to other countries.
