Mathematical Reflection 2

1. a. You can use a table to find the y-intercept and growth factor from an exponential relationship. To find the y-intercept you look or extend the table to when x is 0. You can find the growth factor by finding the relationship between the y section in the table.
b. You use the y-intercept and growth factor to form an equation. You use the form, y=a(b^x). A is the y-intercept and b is the growth factor. You plug the numbers in and form an equation.

2. a. In an exponential relationship you use the equation y=a(b^x). The A is the y-intercept (initial value). B is the growth factor.
b. A is represented because it is the y-intercept .
c. B is represented because it is the growth factor, so it affects the steepness of the curve. It is sort-of like the slope of a line.
