Question 3 of 10
The function a(b) 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) = 12.49
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)=-6
OB. b(a) =
C. b(a) =
O D. b(a) =
-9
+6
+ 9
