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
10. ?
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(e) = 9+5
O B. B(a) = 6-7
O C. B(e) = 8 + 7
O D. B(e) = - 5
