Answer:
Inverse function is
.
Step-by-step explanation:
Given function is
.
Now we need to find the inverse of the given function.
Step 1: replace f(x) with y

Step 2: switch x and y

Step 3: solve for y




Hence required inverse function is
.
Answer:
True.
Step-by-step explanation:
The mode is 7.
Mode means most and 7 hours of sleep is the most frequent.
let the number of sides be n.
Thus,
(n-2)x180=330
n-2=1.83
n=3.83
Rounding off we have, n=4.
Thus the total number of side is 4.
