Answer:
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:
- y= mx+b - slope-intercept form
- m= (y2-y1)/(x2-x1)= (12-16)/(2-1)= -4
See is same slope between second and third points:
- And it is different for the 4th point
So this is not a linear function
Now lets see if y- points have same ratio:
- 16/12= 4/3
- 12/9= 4/3
- 9/6.75= 4/3
So the ratio is same and we have a exponential function
