Question

dentify the conic section, lines of symmetry, and the domain and range.

1. x^2+y2=4



2. x=2y^2+5

Answer 1

what subject is it trig ?

Answer 2

idk if this is right but i got (0,0)

Answer 3

for 1 you mean y^2, not y2, right?

Answer 4

yes

Answer 5

ok, so it is a circle, x and y axis are symmetry lines

Answer 6

okay

Answer 7

2 would be parabola, line of symmetry is y axis

Answer 8

domain for 2 is \[\mathbb{R} \], range is\[\left[ 5,\infty\right]\]

Answer 9

no, I screw up! range is R, domain is 5 to inf

Answer 10

:) what about the second one

Answer 11

the second one is done. I left the domain and range of first one for you to figure out, that should be simple enough

Answer 12

okay thank you
