Question

which equation has a semetry of x=1/5?
y = −5x2 − x + 2

y = −5x2 + x + 2

y = −5x2 + 2x − 9

y = −5x2 − 2x − 9

Answer 1

turn them to standard form

Answer 2

vertex must be 1/5. ok??

Answer 3

yes

Answer 4

y=ax^2+bx+c vertex=-b/a follow that.

Answer 5

uh

Answer 6

y = −5x2 + 2x − 9 this ok but you try to compute !

Answer 7

? i am confused

Answer 8
