Answer:
- f⁻¹(x) = 1/7x² + 3
Step-by-step explanation:
<h3>Given</h3>- f(x) =
- Inverse of f(x)
<u>Change f(x) → x, and x → y, and solve for y:</u>
- x =
- x² = 7y - 21
- 7y = x² + 21
- y = 1/7x² + 3
<u>y = f⁻¹(x)</u>
- f⁻¹(x) = 1/7x² + 3
Answer:
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is
Step-by-step explanation:
Time (months) Views
0 50
2 313
4 1950
6 12,210
8 76,300
10 476,800
Slope =131.5
Slope =818.5
Since the slope is not same . So, it is not a linear relationship
Since the ratio between the consecutive outputs is same so, it is exponential relationship.
Formula :
Where a is the initial value = 50
b = rate of change = 6.25
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data
So
