For each function, use the slope formula to calculate the rate of change between the points. In your final answer, include all of your calculations.
(a, f(a)) and (b, f(b))
1.) f(x) = 130, f(0)) and (6, f(6))
2.) f(x) = -2 (-4, f(-4)) and (2, f(2))
3.) f(x) = x2 (-2, f(-2)) and (0, f(O))
4.) f(x) = 23
(-1, f(-1)) and (1, f(1))
5.) f(0) = 20 (0, f(0)) and (4, f(4))
