Answer
${f(-3)=3}$
${f(3)=3}$
${f(0)=-6}$
${f(\frac{1}{2})=-\frac{23}{4}}$
Work Step by Step
$${f(-3)=(-3)^2-6}$$ $${f(-3)=9-6}$$ $${f(-3)=3}$$
$${f(3)=(3)^2-6}$$ $${f(3)=9-6}$$ $${f(3)=3}$$
$${f(0)=(0)^2-6}$$ $${f(0)=0-6}$$ $${f(0)=-6}$$
$${f(\frac{1}{2})=(\frac{1}{2})^2-6}$$ $${f(\frac{1}{2})=\frac{1}{4}-6}$$ $${f(\frac{1}{2})=\frac{1}{4}-6\times\frac{4}{4}}$$ $${f(\frac{1}{2})=\frac{1}{4}-\frac{24}{4}}$$ $${f(\frac{1}{2})=-\frac{23}{4}}$$
