Which input value produces the same output value for the two functions on the graph?
x = -3, x = -2, x = -1, x = 3

Solution:

INPUT: Called the domain of the function, is the set of all x-values for which the function is defined.

OUTPUT: Called the range of the function, is the set of all y-values for which the function is defined.

By observing the graph we see that the input value which produces the same output value for the two functions on the graph is the point of intersection of these graph, that is:

x = - 2

y = 1

Therefore, the input value which produces the same output value is x = -2.

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

Summary:

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