The height of a hill, h(x), in a painting can be written as a function of x, the distance from the left side of the painting. both h(x) and x are measured in inches.

h(x) = (x)(x – 13)

what is the height of the hill in the painting 3 inches from the left side of the picture?

inches

For this case we have the following function:

To answer the question, we must calculate the value of h (x) when x equals 3.

We then have to substitute values:

Rewriting the equation we have:

The height of the hill in the painting 3 inches from the left side of the picture is:

Note: The value of the function is negative. It is recommended to review the function again. The result must be positive.
