Question

The graph of a function f is given. Use the graph to answer the question.Use the graph of f given below to find f(-15).

Answer 1

Given the graph of the function.

We will find the value of f(-15)

As shown, the x-axis is divided into sections, the interval between two adjacent points = 5

So, at x = -15, we can see the function intersects with the x-axis

So, the value of the function at x = -15 will be equal to zero.

So, the answer will be f(-15) = 0
