1 answer:
Answer:
5
Step-by-step explanation:
The mean represents an average of all the numbers, so we have . Although that may seem confusing, it's actually pretty easy.
We have a total of five numbers, which are 1, 6, 2, 7, and 9.
We add these numbers up to find the sum, so 1 + 6 + 2 + 7 + 9 = 25
So our final answer will be which can be simplified to 5.

The given function is
f(x)= 0.2 x²
Since f(x) will be defined for all real values of x.
So, Domain of f(x) will be ( x| x is a real number.)→This is set builder notation.
Finding the inverse of f(x):
y = 0.2 x²
→ x²= 5 y
→x = → → Inverse of f(x)
Replacing x by y and y by x,we get inverse of the given function
y = → →Domain x ≥ 0, x∈[0,∞]
Graph of function and its inverse are shown below.
