Find c and a so that f(x)=ca^x f(0)=3 and f(2)=12

The function is:

Step-by-step explanation:

Let's plug in the first point (0,3):

So we have:

Let's use the other point (2,12):

Divide both sides by 3:

Square root both sides:

Exponential functions have positive bases so .

The function is:

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft
