if f(x) =x2
what is the gradient of the secant from x= 2 to x=3?
what is the gradient of the secant from x=2 to x=2.5?
what is the gradient of the secant from x=2 to x=2.01?
Gradient of the secant from x = a to x = b is given by (f(b) - f(a))/(b - a)
So gradient of secant from x = 2 to x = 3 is (3^2 - 2^2)/(3 - 2) → 5
You should now be able to do the others.
