F(x)=x^2-2x-3

Question

plz help me slove this ?

HELP ME I DO NOT UNDERSTAND THIS HELP ME PLZ

Answer 1

Well, you really did not ask a question. All you did was give the equation fort a parabola. So what?
y = x^2 - 2 x - 3
do you want to know where that is zero? Where the vertex is? how it looks?
if you want the two zeros, just factor it
y = (x-3)(x+1)
that is zero when:
x = 3
and when
x = -1

so the vertex is halfway between
x = (3-1)/2 = 1
then y = 1-2-3 = -4
so vertex at (1,-4)

what else about it?
