Let f(x)=−1/2(x+2)^2+5 . What is the average rate of change for the quadratic function from x = −3 to x = 1? Enter your answer in the box.

For every x increase, the y decreases by 1 on average. You can tell this by seeing what the totals are for the two extremes. At -3 the value of y is 4.5 and at 1 the value is .5. Subtract the second number by the first and then divide by 4, which is the change in x.
