We want an exponential equation of the form y = Abx, (b > 0). We need to find the numbers A and b that make the equation true for the coordinates (1, 5) and (3, 35).
First, substitute the values in coordinate (1, 5) for x and y.
y | = | Abx |
? | = | Ab1 |
Next, substitute the values in coordinate (3, 35) for x and y.
y | = | Abx |
|
||
? | = | Ab3 |
