1.a.The growth factor is how fast the slope grows and the steepness of the graph. You can get it by dividing y of any given x value by the y of the x value below that. For example, for a graph with the points (0,1) and (1,4) you would divide 4 by 1 to get a growth factor of 4. To find the y-intercept you take the a in and equation or whatever the y is when x=0 in a graph or table.
1.b.You plug the y-intercept in as a and the growth factor as b.
2.a.A represents the original value or the y-intercept. B represents the growth rate.
2.b.A is the y-intercept of the graph.
2.c.B is how fast the slope grows and how curved the line is.
