Answer

See graphs

Work Step by Step

We are given the function: $f(x)=x^2-6x-1$ Rewrite the function building the square: $f(x)=(x^2-6x+9)-9-1=(x-3)^2-10$ We start graphing the parent function $a(x)=x^2$. Then horizontally shift $a(x)$ 3 units to the right to get $b(x)=(x-3)^2$. Finally, vertically shift $b(x)$ 10 units downward to get $f(x)=(x-3)^2-10$.
