Question

Which input value produces the same output value for the two functions on the graph?

X= -1
X= 0
X=

Answer 1

x = 4 will give you the same output no matter what graph you are using. 

Answer 2

x=4

Explanation:

WE need to find out which input value x value gives the same output value y for the two function f(X) and g(X) on the graph

We look at the point of intersection of both f(x) and g(x)

both graphs intersects at a point (4,3)

It means for the input value x=4 both f(x) and g(x) has same output 3

So input value x=4 produces the same output value for the two functions on the graph.
