What is the y-intercept of function g if g(x) = 2f(x) + 1 ?

A. (0,2)
B. (0,-1)
C. (0,3)
D. (0,1)

What Is The Yintercept Of Function G If Gx 2fx 1 A 02 B 01 C 03 D 01 class=

Sagot :

By evaluating the function in x = 0, we will see that the y-intercept is (0, 3), so the correct option is C.

How to find the y-intercept of a function?

The y-intercept of a function g(x) is given by evaluating the function in x = 0.

So the y-intercept of g(x) is:

y = g(0).

In this case, we have:

g(x) = 2f(x) + 1

The y-intercept will be:

g(0) = 2*f(0) + 1

By looking at the graph, we can see that f(0) = 1, replacing that above we get:

g(0) = 2*1 + 1 = 3

Then the y-intercept is the point (0, 3), meaning that the correct option is C.
