Answer :
For this case we have the following function:
[tex] h (x) = (x) (x - 13)
[/tex]
To answer the question, we must calculate the value of h (x) when x equals 3.
We then have to substitute values:
[tex] h (3) = (3) (3 - 13)
[/tex]
Rewriting the equation we have:
[tex] h (3) = (3) (- 10)
h (3) = -30
[/tex]
Answer:
The height of the hill in the painting 3 inches from the left side of the picture is:
[tex] h (3) = -30
[/tex]
Note: The value of the function is negative. It is recommended to review the function again. The result must be positive.
