Find the vertex, the x intercepts and y intercepts.

f(x)=(x-2)^2-4

Vertex: 2,4

X intercepts: 0,0 4,0

Y intercepts: I didn't know how to get these. Could you explain?

**bobpursley**, Thursday, November 12, 2009 at 8:39pmIsn't the vertex at 0,-4?

y intercepts are when x is zero

y=-2^2-4 or 0

x intercepts are when y is zero

0=(x-2)^2 -4

x-2=+-2

x=0, 4
