Question 5 of 15 Step 1 of 1 Find a formula for the inverse of the following function, if possible. $r(x) = \frac{x^3 + 4}{6}$
Added by Brian A.

Step 1
A function is one-to-one if it passes the horizontal line test, meaning that every horizontal line intersects the graph of the function at most once. In this case, r(x) = (x^3 + 4)/6 is a one-to-one function since it is a strictly increasing function for all x in Show more…
