QuestionFind the domain of the function. f(x)=x2−9f(x)=x^{2}-9

Studdy Solution

STEP 1

1. The function f(x)=x2−9 f(x) = x^2 - 9 is a polynomial function.
2. Polynomial functions are defined for all real numbers.

STEP 2

1. Identify the type of function.
2. Determine the domain of the identified function type.

STEP 3

Identify the type of function. The given function f(x)=x2−9 f(x) = x^2 - 9 is a polynomial function.

STEP 4

Determine the domain of the polynomial function. Polynomial functions are defined for all real numbers. Therefore, the domain of f(x)=x2−9 f(x) = x^2 - 9 is all real numbers.
Solution: The domain of the function f(x)=x2−9 f(x) = x^2 - 9 is: Domain: (−∞,∞) \text{Domain: } (-\infty, \infty)
