Exponential

Step-by-step explanation:

Points are:

(1, 16), (2, 12), (3, 9), (4, 6.75)

Lets assume it is linear function, then get the equation:

See is same slope between second and third points:

So this is not a linear function

Now lets see if y- points have same ratio:

So the ratio is same and we have a exponential function

yes

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
