Let f x x² 5 and g x x 7 Find f x g x A B What is the domain x 7 domain all

Answer :

Final answer:

The functions f(x) and g(x) are defined as f(x) = x² + 5 and g(x) = x - 7.

Both functions have a domain of all real numbers.

To evaluate f(x), substitute x into the equation.

To evaluate g(x), substitute x into the equation.

Explanation:

  • The function f(x) is defined as f(x) = x² + 5.
  • The function g(x) is defined as g(x) = x - 7.

The domain of a function is the set of all possible input values.

In this case, since both f(x) and g(x) are polynomial functions, their domains are all real numbers.

  • To find f(x), we substitute x into the equation f(x) = x² + 5.

For example, if we want to find f(2), we substitute 2 for x: f(2) = (2)² + 5 = 4 + 5 = 9.

  • To find g(x), we substitute x into the equation g(x) = x - 7.

For example, if we want to find g(3), we substitute 3 for x: g(3) = (3) - 7 = -4.
