Question

henry is a painter. he uses the function h(x)=50x - 20 to determine the amount he charges for a painting that took him x hours to make. The inverse function is y= x+20/50. What can the inverse function be used to determine?

Answer 1

x amount of money determines y number of hours to make a painting of that cost.

Explanation:

The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).

(x,y)--->(y,x) in the new function.

If the function determines the amount (y) he makes in x hours. The inverse determines how many y hours it takes to earn x amount of money.
