The function Ab) relates the area of a trapezoid with a given height of 12 and
one base length of 9 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) = 12×b+9/2

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?
O A. B(a) = 2 - 6
B. Bla) = +6
C. Bla) =
!-9
6
D. B(A) = 8 + 9
