Question

Let f(x)=2x^2-3x-5. Use the slope 2h+5 to compute the slope of the secant line through (2,f(2)) and (3, f(3)).

Answer 1

Do you just find the slope like in any other situation or is something else supposed to be used? This is in the section in the start of derivatives.

Answer 2

h is supposed to equal 1 so the answer is 7 but i do not understand how to get 1 for h
