Start with two points A: (2,-6) and B: (2+ h, ?) What is the y-coordinate of B? h² − 4h - 6 - • Because the x-coordinate of B depends on h, the y-coordinate will also depend on h. Compute Ax and Ay Now that we have: A: (2,-6) and B: Compute Ax = h Compute Ay=h²-4h (2+ 2 + h, }(2 + h)² − 5(2 + h) + 3) Compute and Reduce Ax/Ay So then, if Ax = h and Ay = ((2 + h)² − 5(2 + h) + 3) − (−6) ·2² +·2·2h + ½h² + (−5) · 2 + (−5)h + 9 h²+h-5h Compute and reduce Ay Ax 1h-4 Finding the limit Use the steps above to compute the instantaneous rate of change for f(x) at (2,-6), then use your answer to find an equation for the line tangent to f(x) at (2, −6):
