The graph of f(x)=x^2 is shown. use the parabola tool to graph the function g(x)=(1/2x)^2 . to graph a parabola, first plot the vertex then plot another point on the parabola.

The equation given is f(x) = x^2 - 12x + 27

Based on its form, it is a parabola. First, factor the quadratic equation:

f(x) = (x-9) (x-3)

Plot in the x-y plane, assign values of x and solve for the values of y. 

x       y
1       16
2      7
3      0
0      27
-1     40
-2    55     
-3    72

X=y+4 is the answe
