Question

f(x) = 3x2 - 2x + 1, evaluate f(-1).

Answer 1

SOLUTION

GIVEN

$\sf{f(x) = 3 {x}^{2} - 2x + 1 \: }$

TO EVALUATE

$\sf{f( - 1) \: }$

EVALUATION

Here it is given that

$\sf{f(x) = 3 {x}^{2} - 2x + 1 \: }$

Putting x = - 1 in both sides we get

$\sf{f( - 1) = 3 {( - 1)}^{2} - 2.( - 1) + 1 \: }$

$\implies \sf{f( - 1) = 3 + 2 + 1 \: }$

$\implies \sf{f( - 1) = 6 \: }$

FINAL ANSWER

$\boxed{ \sf{ \: f( - 1) = 6 \: }}$
