If [tex]f(x) = 5x - 12[/tex], what is [tex]f(2)[/tex]?

A. 10
B. -2
C. -22
D. 2

Sagot :

To find [tex]\( f(2) \)[/tex] for the function [tex]\( f(x) = 5x - 12 \)[/tex], we need to substitute [tex]\( x \)[/tex] with 2 and then simplify the expression.

1. Start with the given function:
[tex]\[ f(x) = 5x - 12 \][/tex]

2. Substitute [tex]\( x = 2 \)[/tex] into the function:
[tex]\[ f(2) = 5(2) - 12 \][/tex]

3. Multiply 5 by 2:
[tex]\[ 5 \times 2 = 10 \][/tex]

4. Subtract 12 from 10:
[tex]\[ 10 - 12 = -2 \][/tex]

So, [tex]\( f(2) \)[/tex] is:
[tex]\[ f(2) = -2 \][/tex]

Looking at the given possible answers:
A. 10
B. -2
C. -22
D. 2

The correct answer is:
[tex]\[ \boxed{-2} \][/tex]
