Question

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.



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

6 inches
13 inches
30 inches
150 inches

Answer 1

I don't have the formula for h(x) in your question — it's missing from the statement. To find the height 3 inches from the left, you need to evaluate h(3): substitute x = 3 into the given h(x).

If you post the explicit formula for h(x), I will compute h(3) and pick the correct choice. (For example, if h(x) = 2x then h(3) = 6; if h(x) = 10x then h(3) = 30, etc.)
