7-127.
  1. EQUATIONS OF TANGENT LINES Homework Help ✎

    1. Use your slopes from problem 7-126 to write the equation of the line that is tangent to each of the functions at the point when x = 2. Use point-slope form.

    2. Describe how your procedure would have been different in the previous problem if you wanted to calculate the slopes of the tangent lines at x = 5.

First you will need to determine the y-coordinate for each function when x = 2.

Use 5 and f(5) instead of 2 and f(2) .
