Which ordered pairs represent points on the graph of f(x)= -37*? check all that apply.
10 (-2,2)
0 (-1,-1)
(0,0)
o (1,-1)
(6.-2)
(8, -2)

answer:

(0,0) (1,-1) (8,-2)

if you was you was to graph this function you would find these points on the graph

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
