1a. You can use a table to find the y-intercept by extending it until x=0. You can use it to find the growth factor by figuring out the pattern in the x- and y-values. You can use a graph to find the y-intercept by finding the point where the line crosses the y-axis. You can use it to find the growth factor by finding the relationship between different points. In the equation y=a(b)^x, a is the y-intercept and b is the growth factor.

b. The form for an exponential equation is y=a(b)^x, where y=the dependent variable, x=the independent variable and the exponent, a=the y-intercept, and b=the growth factor.

2a. In the equation y=a(b)^x, a=the y-intercept and b=the growth factor.

b. In a graph of y=a(b)^x, a is the y-intercept.

c. In a graph of y=a(b)^x, b is the growth factor and it determines the steepness of the line.
