Question

how to do find the axis of symmetry for y=-1/4 - 4x?

Answer 1

NO axis of symmetry

Answer 2

oops i meant y=-1/4^2 - 4x

Answer 3

Still no

Answer 4

ugh i keep typing it wrong

Answer 5

y=-1/4x^2 - 4x

Answer 6

Diffrentiate and equate to zero

Answer 7

can you show me how to do it?

Answer 8

or it is x=(sum of roots)/2

Answer 9

ok but for me i cant get the roots until i get the axis of symmetry. it turns into 4/(-2/4) for some reason

Answer 10

sum of roots = -coefficient of x/coefficient of x^2
you don't need to find the roots

Answer 11

so if i do do that it would be:
sum of roots= -4/(-1/4) right?
