If the function g(x) = x² - 5, what is g(2)?

If the function g(x) = x² - 5, what is g(2)?

• A. -1
• B. 0
• C. 1
• D. 2

Answer: (A)

To find the value of g(2) using the function g(x) = x² - 5, you substitute x with 2. This gives you: g(2) = (2)² - 5 Calculating (2)² results in 4, so the equation becomes: g(2) = 4 - 5 Now, when you perform the subtraction, 4 - 5 equals -1. Therefore, g(2) = -1. This shows that the correct answer is -1.

To find the value of g(2) using the function g(x) = x² - 5, you substitute x with 2. This gives you:

g(2) = (2)² - 5

Calculating (2)² results in 4, so the equation becomes:

g(2) = 4 - 5

Now, when you perform the subtraction, 4 - 5 equals -1. Therefore, g(2) = -1.

This shows that the correct answer is -1.
