Consider the function f(x) = -5 x - 2 and find the following:
a) The average rate of change between the points (-1, f(-1) ) and (1, f( 1 ) ) .
b) The average rate of change between the points (a, f(a) ) and (b, f(b) ) .
c) The average rate of change between the points (x, f(x) ) and (x+h, f(x+h) ) .

Average rate of change : \(A(x) = \dfrac{f(x)-f(a)}{x-a}\)

where do i find a if like in a) i plug in -1 to the f(x) which is -5(-1)-2

ohh
