Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
