QuestionThe function $g$ is defined by $g(x)=x^{2}+9$. For which value of $x$ is $g(x)=25$ ? A) 4 B) 5 C) 9 D) 13

Studdy Solution
Verify the solutions by substituting back into the function $g(x) = x^2 + 9$:
For $x = 4$: $$g(4) = 4^2 + 9 = 16 + 9 = 25$$
For $x = -4$: $$g(-4) = (-4)^2 + 9 = 16 + 9 = 25$$
Both values satisfy the equation $g(x) = 25$.
The value of $x$ that is listed among the options and satisfies $g(x) = 25$ is:
$$\boxed{4}$$
