Question

for the given function, compute the average rate of change
f(x2)-f(x1)/x2-x1 with x1= a and x2 = a+h

1) f(x) = -3x^2 + 2x - 5

Answer 1

\[\frac{-3(a+h)^2+2(a+h)-5-[-3a^2+2a-5]}{h}\]

Answer 2

then a bunch of algebra to clean up the numerator
you should be left only with terms than include an \(h\)
then you can divide by \(h\)

Answer 3

this clears it up for me. Thank you!
