1. Calculate the first and second differences for y = x²+ 7x + 6.

2. Given the following graph and the values ofhandk, determine its equation.

h = 2; k = 3

3. Using the graph of y = 2^x, you will have to put this into demos it is a free graph calculator that describes some of its properties. Relate these properties to the graph.

4.As part of the school's social justice outreach club, Kadesha volunteers each week to tutor a student in grade 10 math. She is trying to explain to David how to best understand first and second differences. David also wants to know how to tell the difference between a linear and a quadratic relation using first and second differences. Put yourself in Kadesha's place and outline the process you would use in doing this.

5. Explain the effect of a, h and k on the graph of y = a(x - h)²+ k. Be sure to note what happens if a has value of "0".

6. Graph y = x², y = 2x²; y = -2(x + 1)²; and y = -2(x + 1)²on the same axes Be sure to label each graph. Explain the relationship between each.
