The domain of the inverse of a function is the range of the original function
so find the range of f(x)
this is lowest to highest
we got the vertex is at (0,4)
and it goes to infinity
so range is from 4 to infinity
inverse
replace f(x) with y
switch x and y
solve for y
replace y with finverse
f(x)=x^2+4
y=x^2+4
x=y^2+4
x-4=y^2
y=√(x-4)
f⁻¹(x)=√(x-4)
inverse is f⁻¹(x)=√(x-4)
the domain is x≥4
√4 + <span>3√9 = 2+3*3 = 11.
This is a rational number, since the answer can be express as a fraction (e.g., 11/1).
This does not hold for square roots in general. For example </span>√3 is irrational.

Answer:
5.2 inches
Step-by-step explanation:
The diameter of small Nerf balls follows normally distribution with mean 5.2 inches and standard deviation 0.08 inches.
We have to calculate the mean of sampling distribution when 20 balls are selected randomly.
Here, μ=5.2 and σ=0.08.
We know that mean of sampling distribution for mean is equal to the population mean.
mean of sampling distribution for mean= μxbar=μ= 5.2
Thus, mean of the sampling distribution of the sample mean is 5.2 inches
