The function A(b) relates the area of a trapezoid with a given height of 10 and one base length of 7 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) = 10.bz?
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. Bla) = -7
O B. B[a) = 3 +5
c. Bla) = 9 -5
O D. Bla) = 3 +7
