Question

Verification of answer needed please:
Using a(x-h)²+2: ===> f(x) = x²-4x +2; Find X-int\Y-int; Vertex\Line of Sym.
so here's what i got:
a) x-int = x = 2 ±√2 ==> (3.41,0) and (.54,0)
b) y-int = (0,2) < 15 years ago

Answer 1

a) looks correct
b) is correct, because f(0) = 2
c) is correct
d) is correct

Answer 2

:D yay thanks
