Im stuck on this problem and don't know what to do.
Using the formula for the slope of a secant line passing through two points on a curve f(x+h)-f(x)/h determine this secant line slope formula for the function f(x)=3x^2-5x. Yu must simplify your result algebraically.
Ok, write
f(x) = 3x^2-5x
f(x+h) = ?
Now think of x+h as a single number (because that's what it is). So you understand that
f(7) = 3(7)^2-5(7) right?
Now using the same method, try to replace the question mark below with the appropriate expression
f(x+h) = 3(x+h)^2 - 5(x+h)
So whould I continue and do f(x+h) - f(x)/h and get 6x + 3h -5 in the end?
