In an earlier discussion Ms Coombs had the
students find the equation of the line that
connected the left points of each step of
the rate of change step function. She
also had them find the equation of the line
connecting the right end points of each step
of the step function.
Ms Coombs continues to discuss the pattern
to find the rate of change function for a
given quadratic function.
Day 4 - Clip 3
Ms Coombs continues to discuss the pattern to
find the rate of change function for a given
quadratic function. Here, she presents the
function in the generalized form y = ax2
+ bx +c. The students disagree over the answer.
