Given :
- f(x) = 2x - 3
To Find :
- f(-2) = ?
Solution :
As, f(x) = 2x - 3
Therefore, f(-2) = 2(-2) - 3
[tex]\sf : \implies f(-2) = 2(-2) - 3[/tex]
[tex]\sf : \implies f(-2) = - 4 - 3[/tex]
[tex]\sf : \implies f(-2) = - 7[/tex]
Hence, value of f(-2) is - 7.
Substitute-2 for x in the equation and get 2•-2=-4 then subtract 3 from -4, -4-3=-7 so the answer is -7
