Use the following information to answer questions 48–50.

The quadratic function f and △MPQ are graphed in the standard (x,y) coordinate plane below. Points M(2a, 5b), N(4a, 9b), and P(6a, 5b) are on f. Point Q(4a, 0) is NOT on f.

48. In terms of a and b, what is the area, in square coordinate units, of △MPQ ?

Answer and Explanation

Your Answer is

Correct Answer is G

Explanation

S = 0.5×(6a-2a)×5b = 10ab
