Question

Evaluate f(2). f(x) = 3x - 1

Answer 1

5

Explanation:

`f(x) = 3x - 1`

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

Just replace the x with 2

I think this is the right way to do it

Answer 2

Given:-

• 
  `\sf \: f ( x )= 3x - 1`

`\:`

To find:-

• 
  `\textsf{f ( 2 ) = ?}`

`\:`

Solution:-

• 
  `\textsf {f ( x ) = 3x - 1 }`

`\:`

put the value of x= 2 in equation:

• 
  `\textsf{f ( 2 ) = 3( 2 ) - 1}`

`\:`

• 
  `\textsf{f ( 2 ) = 6 - 1}`

`\:`

• 
  `\underline{ \boxed{ \textsf \purple{f ( 2 ) = 5}}}`

`\:`
