Given:

[tex]y=x^2-3x-4[/tex]

1) Function notation

[tex]f(x)=x^2-3x-4.[/tex]

2) put x=-2

[tex]\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}[/tex]

3) Put x=-1

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

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

when x =0 f(x)=-4

when x=3 f(x)=-4
