Evaluate the following functions by filling up the missing parts of the solution

f(x) = 3x - 5, find f(2)
Solution:
f(2) = 3*(2) - 5 = 6 - 5 = 1
Option 1: f(2) = 6 - 5 = 1
Option 2: f(2) = 3*(2) - 5 = 6 - 5 = 1
Option 3: f(2) = 3*(2) + 5 = 6 + 5 = 11
Option 4: f(2) = 2*(3) - 5 = 6 - 5 = 1

Answer 1

To evaluate f(x) = 3x - 5 for f(2), substitute 2 for x to get f(2) = 3*2 - 5, which simplifies to 6 - 5, resulting in the answer of 1. Therefore, the correct option is Option 1: f(2) = 6 - 5 = 1.

Step-by-step explanation:

To evaluate the given function f(x) = 3x - 5 for f(2), you simply substitute the value of x with 2:

Solution:

f(2) = 3*(2) - 5 = 6 - 5 = 1

This step-by-step calculation shows that the correct answer is Option 1:

• f(2) = 6 - 5 = 1

Let's dismiss the incorrect options:

• 
  
• Option 3 is incorrect because it uses addition instead of subtraction.
• 
  
• Option 4 is simply a rearrangement and delivers the same answer as Option 1, but is less direct.

Multiplication rules, as seen in evaluating f(2), dictate that two positive numbers multiply to a positive number (2x3 = 6), and the result of subtracting a positive number (5) from another positive number (6) is the difference (1).
