Answer

a. $f(0)=-2$ b. $f(-3)=-20$ c. $f(\frac{1}{3})=-\frac{10}{9}$

Work Step by Step

$f(x)=-x^2+3x-2$ a. $f(0)=-(0)^2+3(0)-2$ $f(0)=-2$ b. $f(-3)=-(-3)^2+3(-3)-2$ $f(-3)=-9-9-2$ $f(-3)=-20$ c. $f(\frac{1}{3})=-(\frac{1}{3})^2+3(\frac{1}{3})-2$ $f(\frac{1}{3})=-\frac{1}{9}+1-2$ $f(\frac{1}{3})=-\frac{10}{9}$
