Tir Consider the parabola p(a) - -2.8x2 + 2.8x + 16.8. For which interval [A, B] is B p(x) dx as large as possible? A note about the choices: for some incomprehensible reason eClass sometimes switches the position of A and each option very carefully, as your interval might be a backwards version of what eClass is showing as an option O a. [2.5000, -2.5000] O b. [-2.8. 2.8] O c. [0.5000 , -0.5000] O d. [2.00000, -3.00000] O e. [5.3000, 0.3000] NIf f(1) = -8.9, f'(x) is co.. .inuous, and ffff'(x)dx = -19.5, what is the value of f(4)?
