Answer:

$f(-1)=7$

Step-by-step explanation:

I am going to assume your question meant the equation

$f(x)=2x^{2} -4x+1$

So $f(-1)$ can be found by substituting all the x terms in the equation with -1

$f(-1)=2(-1)^{2} -4(-1)+1$

And simplifying for our answer

$f(-1)=2(1)+4+1$

$f(-1) = 2+4+1$

$f(-1)=7$
