Consider the linear function f(x) = mx + b , where m≠0 , on the interval [3, 7] . explain why the maximum value of the function over this interval must occur at one of the endpoints of the interval.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
