What is the range of the function
f(x) = = 3x + 2 in the domain -2

What Is The Range Of The Functionf(x) = = 3x + 2 In The Domain -2

Answers

Answer 1

Answer:

The range is:

{-4, 1, 2, 5, 8}

Step-by-step explanation:

Given the function

[tex]f(x)=3x+2[/tex]

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

As the domain interval -2 ≤ x ≤ 2

i.e. the values in the domain = {-2, -1, 0, 1, 2}

We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

As the domain interval -2 ≤ x ≤ 2

Putting all the x-values in the domain interval in the function

so

putting x=-2 in the function

[tex]f(x)=3x+2[/tex]

[tex]f(-2)=3(-2)+2=-6+2=-4[/tex]

putting x=-1 in the function

[tex]f(x)=3x+2[/tex]

[tex]f(-1)=3(-1)+2=-3+2=1[/tex]

putting x=0 in the function

[tex]f(x)=3x+2[/tex]

[tex]f(0)=3(0)+2=0+2=2[/tex]

putting x=1 in the function

[tex]f(x)=3x+2[/tex]

[tex]f(1)=3(1)+2=3+2=5[/tex]

putting x=2 in the function

[tex]f(x)=3x+2[/tex]

[tex]f(2)=3(2)+2=6+2=8[/tex]

Thus, when we put the domain values, the corresponding range values are:

x           y

-2         -4

-1           1

0           2

1             5

2            8

Therefore, the range is:

{-4, 1, 2, 5, 8}

Answers

Answer:

Step-by-step explanation:

2a+1/3a + 5/4 -2a-3/6a^2

=4(2a+1)+15a/12a - 2a-3/6a^2

=a(8a+4+15a^2)-{2(2a-3)}/12a^2

Sara says, "If you subtract 14 from my number and multiply the difference by - 3, the result is – 42."
What is Sara's number?
Sara's number is |

Answers

Answer:

Sara's number is 28

Step-by-step explanation:

Let's assign Sara's number the variable x and solve this equation using the information provided.

"If you subtract 14 from my number"

x - 14

"and multiply the difference by - 3"

-3(x - 14)

"the result is – 42."

-3(x - 14) = -42

Now we can solve from here for x.

-3(x - 14) = -42

x - 14 = 14

x = 28

Anna purchased a new car for $25,000. The car will decrease in value 15% each year.
The value of Anna's car is modeled on the graph by function f where x is the time in years after Anna purchases her car.

Answers

I will assume that we want to find the function that predicts the value of the car after x years, which likely is an exponential decay.

The function is: f(x) = $25,000*(0.85)^x

And the graph can be seen at the end of the answer.

We know that the value of the car decreases by 15% each year, then we can model this with an exponential decay.

The general exponential decay is given by:

f(x) = A*(1 - r)^x

Where:

A is the initial value, then we have A  = $25,000

x is the variable, in this case, would represent time in years.

r is the rate of decay, in this case, is the quotient between the percentage that decreases and 100%, so we will get: r = 15%/100% = 0.15

Then the exponential equation is:

f(x) = $25,000*(1 - 0.15)^x

     = $25,000*(0.85)^x

This is the function that models the value of the car after x years, the graph can be seen below.

whole squares = 12

half squares = 4 (which equals 2)
