To findf(a+h)-f(a)hthen utilize the results to write the desired quotient.-given f(x)= 9x2 - 11x + 2, it is easiest to first find both f(a+h) and f(a). We canWe begin by calculating f(a+h). For that, we substitute a + h for x, expand the parentheses, combine liketerms, and simplify.9x² - 11x + 2f(a+h) = 9(a+h)² - 11(a+h) + 2=9a² +X +9h²-11a - 11h+2
