2.4 Rates of Change and Tangent Lines Goal: Find the average rate of change of a function over an interval. Find the slope of the curve at the indicated point. Determine whether the curve has a tangent at the indicated point. Find the equation of the tangent line and normal line.
1. Find the average rate of change over the given intervals. • a) [-1,3] b) [-2,-1]
3. Find the slope of the curve • Instantaneous rate of change
Definition of a Tangent Line Use point slope to write equation of the line 1,2,3
4. Find the equation of the tangent line if it exists • when x=4 4
5. Find the equation of the tangent line if it exists • at x=0 • Hint: Find the left handed limit and the right handed limit. 5,6
6. Free Fall (m/s) • An object is dropped from a cliff 450 meters above the ground. The height above the ground after t seconds is • after falling. • Instantaneous:
7. Find the rate of change of a square with sides 4 inches The rate of change is the Area/radius Therefore
Last Question!! • Find the point where there is a horizontal tangent: 7
