What is the domain and range for the following function and its inverse?

f (x) = x2 + 3

Function:

f (x) = x² + 3

The domain is the maximum and minimum values of x that can be put into a function to yield another value. In this case, the domain is negative infinity to positive infinity

D = (∞,-∞)

The minimum value of the function is when x is 0

The minimum value is 3

The maximum value is ∞

Therefore, the range is [3, ∞)

For the function's inverse, the original domain will become the range and the original range will become the domain.
