Question

graph the function . identify the axis of symmetry.
            2   
y=(x-3)  -4

anonymous · Answer

Is this meant to be read as $$y=(x-3)^{2}-4$$

anonymous · Answer

yes

anonymous · Answer

Alrighty. Then this will be a parabola with a y-intercept at -4 and a line of symmetry at +3. The cool thing about having the equation in that form is that you can quickly see where it's shifted too (the line of symmetry) and the y-intercept. 

Can you plug in numbers from there?

using transformations,  this graph will look exactly like $\ y=x^2 $  but translated 3 units to the right, and 4 units down.
the y-intercept will be at y=5, x-intercepts at x=1, 5.
