EQUATIONS OF TANGENT LINES

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

. Use point-slope form.First you will need to determine the

for each function when.Describe how your procedure would have been different in the previous problem if you wanted to calculate the slopes of the tangent lines at

.Use

and instead ofand .
