Question

Which input value produces the same output value for the

two functions on the graph?
wawiening value produces the same suur value for the
O x=-1
O x = 0
X=1
x
x
= 2

Answer 1

The input value that produces the same output value for the two functions on the graph is x = -2

It's important to know some concepts:

1. INPUT: Also called the domain of the function, it Is the set of all x-values for which the function is defined.

2. OUTPUT: Also called the range of the function, it is the set of all y-values for which the function is defined.

So we need to know which of the following inputs produces the same output value for the two functions on the graph

x=-3

x=-2

x=-1

x=3

By looking at the graph we can realize that the input value that produces the same output value for the two functions on the graph is the point of intersection of these graph, that is:

the point at x=-2

And the output value is the y-value:

y=1
