Answer:

x = -7 and x = 2

Step-by-step explanation:

Look for the points on the graph where if you draw a horizontal line at y=1, you will intersect the curve.

By observation, we can see that this happens at x = -7 and x = 2

x = -7 and x = 2

How to elaborate the problem ?

Here in the diagram, we can see that, a curve is present & 6 co-ordinates on that curve are given.

We have to find the values of x correspond with f(x) = 1

What are the input values ?

f(x) = 1 means y = 1

So, if we draw a horizontal line at y = 1, which is parallel to x-axis.

Then, we can able to observe the points which are on the line y = 1.

So, the points on line y = 1 are (-7, 1) & (2, 1).

Hence, we can say that, input values that correspond with f(x) = 1 are x= -7 & x = 2.
