Question

If f(x) = 3x - 5, then what is the value of f(5)?

Answer 1

10

Explanation:

Step 1: Plug in the values.

• 
  `f(5) = 3(5)-5`

Step 2: Multiply 3 by 5.

• 
  `f(5) = 3(5) - 5`
• 
  `f(5) = 15 - 5`

Step 3: Subtract 5 from 15.

• 
  `f(5) = 15 - 5`
• 
  `f(5) = 10`

Therefore, f(5) = 10.

Answer 2

f(5) = 10

Explanation:

f(x) means that x is put into the variable on the right.

f(5) means that 5 is put into the variable on the right. So you put a 5 in where you see an x on the right.

f(5) = 3*5 - 5

f(5) = 15 - 5

f(5) = 10
