Question

Which input value produces the same output value for the

two functions on the graph?
X=-1
X=0
X=3
X=4

Answer 1

x = 4

Explanation:

The 2 graphs have the same output, y = 3 at the point of intersection

This occurs when the input is x = 4

Answer 2

Option D.

Explanation:

The given graph shows the two functions.

Red line represents the function f(x). From the given we conclude that

`f(-1)=3`

`f(0)=3`

`f(3)=3`

`f(4)=3`

Blue line represents the function g(x). From the given we conclude that

`g(-1)=-0.75`

`g(0)=0`

`g(3)=3.25`

`g(4)=3`

Since f(4)=g(4)=3, therefore at x=4 the function have same output values.

Thus, the correct option is D.
