Question

find x intercepts if any for the graph of the quadratic function f(x)=(x+2)^2-4

Answer 1

\((x+2)^2-4=0\)
can you solve that?

Answer 2

x=0

Answer 3

and?

Answer 4

when you plug in your zero it is it is 0=0

Answer 5

there is more than one

Answer 6

but you need to solve it

Answer 7

\((x+2)^2-4=0\implies (x+2)^2=4\implies x+2=\pm\sqrt{4}\implies x=\pm 2-2\)

So \(x=-2-2\) and \(x=2-2\)

Answer 8

yes I see thanks
