Question

F(x) =
2/9x2+18x-216

Answer 1

Domain: all real numbers

Explanation:

The function is:

`f(x) = (2)/(9)x^2 + 18x - 216`

The domain of a function is the set of values of the x-coordinates of the points of the function.

In this function, there is no restriction on x, so the domain is all real numbers.
