The function A(b) relates the area of a trapezoid with a given height of 14 and one base length of 5 with the length of its other base.
It takes as input the other base value, and returns as output the area of the
trapezoid.
A(b) = 14.5+5
Which equation below represents the inverse function B(a), which takes the
trapezoid's area as input and returns as output the length of the other base?
A. B(a) = 15
B. B(a) = 7
O C. B(a) = 9-5
D. B(a) = -2
