What is the value of f(-2) if f(x) = - 3x2 + 4x - 1
pashok25 [27]

Given the function below:

\large{f(x) =  - 3 {x}^{2}  + 4x - 1}

To find f(-2), we substitute x = -2 in the equation. Since f(-2) means the value of f(x) at x = -2.

\large{f( - 2) =  - 3 {( - 2)}^{2}  + 4( - 2) - 1}

Replace x-term to -2 and evaluate.

\large{f( - 2) =  - 3(4) - 8 - 1} \\  \large{f( - 2) =  - 12 -  8 - 1 \longrightarrow f( - 2) =  - 21}

Answer

  • f(-2) = -21

Let me know if you have any doubts!
