Question

Consider the two functions given below.

f(x)=-3x-5
g(x)=f(x)+9
what is the y-intercept of g?

Answer 1

Answer: 4

Reason:

Plug x = 0 into f(x)

f(x) = -3x-5

f(0) = -3*0-5

f(0) = 0-5

f(0) = -5

This then means,

g(x) = f(x)+9

g(0) = f(0)+9

g(0) = -5+9

g(0) = 4

The y intercept of g(x) is 4; meaning it is located at (0,4).
