Question

The graph of which quadratic equation is shown below? Graph Attachd in comment...


Answer
y = x^2 - 2x - 3
y = x^2 + 2x - 3
y = -x^2 + 2x - 3
y = -x^2 - 2x - 3

Answer 1

i'm stretching my memory here...
i think you can do this by considering transformation of y=x^2
moving 1 to left gives (x+1)^2
then down 4 gives y = (x+1)^2 - 4

this is y = x^2 + 2x + 1 - 4

so is this one of the options?
