Question

question 3 of 10
if ( f(x) = 5x - 12 ), what is ( f(2) )?

a. ( -2 )
b. ( 10 )
c. ( -22 )
d. ( 2 )

Explanation:

Step1: Substitute x = 2 into f(x)

To find \( f(2) \), we substitute \( x = 2 \) into the function \( f(x)=5x - 12 \). So we get \( f(2)=5\times2 - 12 \).

Step2: Calculate the expression

First, calculate \( 5\times2 = 10 \). Then, subtract 12 from 10: \( 10-12=-2 \).

Answer:

A. -2
