a) From a table you can find the y-intercept because when x equals zero it's the y-intercept. You can find the growth factor by dividing one number by the number before it on the graph. Then use the answer to see if it works as the growth factor for the rest of the numbers.
From a graph you can find the y-intercept just by looking where the line crosses the y-axis. You can find the growth factor by seeing how many spaces go up each time it goes up by one.
From and equation you can find the y-intercept by looking at the a in y=a(b)^n. You can find the growth factor by looking at the b.
b) Use the y-intercept as the a and use the growth factor as the b.
2.
a) A represents the y-intercept except when c changes it. B represents the growth factor.
