Question

(PLEASE ANSWER + 10 POINTS!!!)

The graph in the xy‑plane below represents the function a graphic designer uses to position the outer edge of a rainbow on a billboard, where x represents feet from the left edge of the billboard and y gives the feet above the lower edge of the billboard. The rainbow begins at the left edge and ends at the bottom edge of the billboard. How many feet from the lower left edge of the billboard does the rainbow end?

A. 7 feet

B. 10 feet

C. 40 feet

D. 48 feet

Answer 1

I believe it would be C. 40 feet.

Answer 2

The rainbow ends at 40 feet

Explanation:

As we can see in the figure, the x axis is showing the distance in feet while the y axis shows the height of the rainbow. The rainbow starts from the left edge and ends on the right edge at point 40 on the x axis. So we can say that the rainbow ends at 40 feet from the starting point shown on the left edge.
