Secants+and+Tangents



This lovely graph shows the Secant/Tangent Investigation we did on September 23rd. Woot!

=Question=

Find the points of intersection between the given points and the function y= 6 (x-2)^2 -6 and detrmine their slope and whether it is a tangent or secant line.

a. (5,0) (0,-2) b. (5,0) (4,-6) c. (5,0) (2,-6)

Have fun!

a.) m=0.4 (secant, therefore average rate of change) b.) m= -1 (secant) c.) m= -2 (secant)
