Question

evaluating functions - evaluate the function for the given values. no calculator. f(x) = -3(x + 7) f(2) =??? only type the numeric answer

Explanation:

Step1: Substitute x = 2 into the function

We have the function \( f(x) = -3(x + 7) \). To find \( f(2) \), we substitute \( x = 2 \) into the function. So we get \( f(2) = -3(2 + 7) \).

Step2: Simplify the expression inside the parentheses

First, calculate the value inside the parentheses: \( 2 + 7 = 9 \). Now the expression becomes \( f(2) = -3\times9 \).

Step3: Multiply the numbers

Multiply -3 and 9: \( -3\times9 = -27 \).

Answer:

-27
