Find each function value.f(x)=2-x

_{2}

(a)*f*(28) =

(b)*f*(8) =

(c)*f*(-6) =

(d)*f*(0.3) = - November 5th 2012, 10:53 AMfkfRe: please help me to understand this?
I'll help you with the first one and hopefully you'll have the idea.

f(x)=2-x2 => f(28) = 2-(28)^2 = -782 - November 5th 2012, 11:06 AMimpressu2Re: please help me to understand this?
I am able to solve them all except -6, I keep getting -38 and it says that it's incorrect.
