What is the range of the function f(x) = 3.2x for the domain {-4, -2, 0, 2, 4}? {-12.8, -6.4, 0, 6.4, 12.8} {12.8, 5.5, 0, -6.4, -12.8} {0, 6.4, 12.8, 19.2, 25.6} {-12, -6, 0, 6, 12}

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

7,24
