Y=x^2-2x-2 , find the vertex, y-intercept, and axis of symmetry

vertex=(1,-3)

y-intercept=(0,-2)

x-intercept=(1,+\sqrt{3},0)

axis of symmetry= 1

the first option is the answer.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
