Question

Given Given, find f(x) = 2x + 9, find (1)

Answer 1

• 
  `\sf f(1) = 11`

Explanation:

To find f(1) when f(x) = 2x + 9, we first need to substitute x with 1 in the equation and solve for f(1).

Let's plug in x = 1 into the equation :-

• 
  `\sf f(1) =2(1)+9`

Simplify the expression :-

• 
  `\sf f(1) = 2+9`

• 
  `\sf f(1) = 11`

Therefore, when x = 1, f(x) is equal to 11.
