Let f(x)=-x-5 and g(x)=2x+3. Find the indicated value:
x when g(x)=1

Answers

Answer:

-9

Step-by-step explanation:

few words about function notation. If f is a function, then f(x) is the

value of the function at x, usually denoted by some sort of rule for finding

the value of the function given that you know the value of x. f(a) would be

the value of the function at a, and f(4) would be the value of the function at,

=4

In this case the value of the function f at x, or f(x) is given by the rule:

f(x) = -x - 5 You want to know f(4), which is the value of the function at

4, so f(4) = -(4) - 5 = -9
