Question

What is the value of the function at x = 2?

Enter your answer in the box.

Answer 1

-3

Explanation:

We are given that a graph.

We have to find the value of the function at x=2.

To find the value of function at x=2 we will find the value of y corresponding to x=2 by drawing a vertical line x=2

The given graph is the graph of a line.

We can see that when we draw a vertical line x=2 and parallel to y- axis.

Then, the vertical line x=2 cut the given line at pint (2,-3).

Therefore, the intersection point of line x=2 and the given line is (2,-3).

The value of y corresponding to x=2 is -3.

We know that
`y=f(x)`

`f(2)=-3`

Therefore, the value of the given function at x=2 is -3.

Hence, the value of the function at x=2 is -3.

Answer 2

y = - 3

Explanation:

Locate x = 2 on the x- axis, then go down vertically until the line is met.

Then read the corresponding y- coordinate at this point.

When x = 2 the value of the function is y = - 3
