Question 335804: for the function with the rule f(x) = x^3 - 3x+3, the gradient of the chord which connects the points x = 2 and x = 3 is?
it would be great if you could show the working out thanks

You can put this solution on YOUR website!
Calculate f%282%29.
f%282%29=2%5E3-3%282%29%2B3
Calculate f%283%29 similarly.
Now you have two points, (2,f%282%29) and (3,f%283%29).
Use the formula for the slope (gradient) of the line connecting the two points,
m=%28f%283%29-f%282%29%29%2F%283-2%29=f%283%29-f%282%29
