An incomplete table of values for an exponential function is shown. The exponential function is of the form y=a\cdot b^x where a is a real number such that a\ne0 and b is a positive real number not equal to 1. Enter the values of a and b in the boxes given below, then complete the table with possible values for the exponential function.

X- 0-1-2-3
Y-96

−3−99

because if

+0−1−2−3−96

x+0−1−2−3−96

−99−3

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

b) well because you get well
