for this problem, given a function Y equals f of X. We need to find a slope of the second line passing through the point P&Q. With p having coordinates three up of three in Q with coordinates X. F of X. Also, we need to find the slope of the tangent line at P. I consider this arbitrary graph of the function with points P and Q in it, the line passing through points B and Q. Is the second line drawn here. Know that the slope of this line is just the change and why over the change in X. And so the slope of the second line through points P and Q is F of X -F. L. three over x minus three. For part B. We draw the tangent line at P know that as a cube gets closer to P, the second lines form slowly follows the form of the tangent line at P. So the limiting value of the slope of the second line through P and Q is equal to the slope of the tangent line at P. That means the slope of the tangent line at P. This is equal to the limit of f of x minus ever. Three Over X -3. As X approaches three
