Let f(x)=x^2−2x−4. What is the average rate of change for the quadratic function from x=−1 to x = 4? Enter your answer in the box. I NEED THIS ANSWERED ASAP

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6
