**Reiny**, Sunday, December 16, 2012 at 11:04pmI will do the last one, you do the first two in the same way ...

f(-2) = (-2)^2 + 4 = 8

f(1) = 1 + 4 = 5

rate of change = ( f(x2 - f(x1))/(y2 - y1)

= (5-8)/(1-(-2)) = -3/3 = -1

(notice I could have done:

(8-5)/(-2 - 1) = 3/-3 = -1 to get the same result )
