1a. The growth factor of an expenentionally grown line is the steepness. It shows how fast it goes up for example doubling or tripleing. To find it in in a table you divide y when x equals 2 by y when x equals 1. To get it from a graph you do the same thing from the table exept you have to find the points. From the equation: Y= a(b to the x) the growth factor is the b. To find the y intercept in a table or graph you take the number when x is zero. To find it from the equation you fill in 0for x or take the a value.
1b. You fill in the Y intercept as the a value and the growth factor for the b value.
2a. A is the y intercept b is the growth factor.
2b. A is the spot where x equals 0.
2c. B is how rapidly the line is going up.
