Question

What is the directrix of the parabola with the equation y+3+1/10(x+2) squared?

Answer 1

what the?

Answer 2

so @KelseyCK where's the " = " sign in that parabolic EQUATion?

Answer 3

maybe a quick screenshot would do :)

Answer 4

There is not an = sign @jdoe0001

Answer 5

@jdoe0001 I'm sorry the equation is actually y+3=1/10(x+2)squared

Answer 6

\(\large \bf y+3=\cfrac{1}{10}(x+2)^2\quad ?\)

Answer 7

yes @jdoe0001

Answer 8

\(\bf y+3=\cfrac{1}{10}(x+2)^2\implies y+3=\cfrac{(x+2)^2}{10}\implies 10(y+3)=(x+2)^2\)

can you see the vertex coordinates of the parabola there?

Answer 9

no...

Answer 10

I'm just not understanding the question itself and am unsure on how to solve the equation

Answer 11

im sorry, @KelseyCK

Answer 12

Go away oh my gosh @Dbzfan836
