Given:


y=x^2-3x-4

1) Function notation


f(x)=x^2-3x-4.

2) put x=-2


\begin{gathered} f(-2)=(-2)^3-3(-2)-4 \\ f(-2)=2^2+3\cdot\: 2-4 \\ f(-2)=4+6-4 \\ f(-2)=6 \end{gathered}

3) Put x=-1


\begin{gathered} f(-1)=(-1)^3-3(-1)-4 \\ f(-1)=1+3-4 \\ f(-1)=0 \end{gathered}

4) f(x)=-4 to find x.

when x =0 f(x)=-4

when x=3 f(x)=-4
