Time The average value of a function f(x) over the interval [a,b] can be found using 1 fave = f(x) dx a - b Select one: O True False NTime left 0: Consider the parabola p(a) = -7.7x2 + 3.9x + 7.4. For which interval [A, B] is . B as large as possible? A note about the choices: for some incomprehensible reason eClass sometimes switches the position of A and B. Read each option very carefully, as your interval might be a backwards version of what eClass is showing as an option. O a. [4.9125, 2.8875] O b. [1.0125, -1.0125] O c. [0.75926, -1.26575] O d.
