Question

What is the value of the function at x = 3?

Enter your answer in the box.

Answer 1

When x is 3, y is 4
To do this, go to the right 3 units and go up until the line intersects with a grid point
At three, y is 4
Hope this helps!

Answer 2

The value of the function at x=3 is 4.

Explanation:

Consider the provided graph of the function.

We need to find the value of the function at x=3

In order to find the value of the function at x=3 first move right to the origin by 3 unit.

Now draw a perpendicular line at x=3

The point where both lines intersect is the required value of the function.

For better understanding refer the figure.

Since the both lines intersect at (3,4), that means the value of the function at x=3 is 4.
