Which is the best estimate for the average rate of change for the quadratic function graph on the interval −3 ≤ x ≤ −2?

-5a+b

Step-by-step explanation:

A general quadratic function of x is given by f(x) = ax² +bx +c

Now, the rate of change of the quadratic function f(x) is given by .

Therefore, = 2ax +b.

Now, the value of x ranges between -3 ≤ x ≤-2.

So, at x= -3, = 2a(-3) +b = -6a +b

And at x= -2, = 2a(-2) +b = -4a +b

Therefore, the average rate of change will be given by . (Answer)
