Question

Find the axis symmetry of the parabola formed by the following quadratic function: y=3x^2+7x-4 a.)x=7/3 b.)-7/3 c.)x=7/6 d.)-7/6

Answer 1

hey this almost the same one!

Answer 2

remember the vertex was right in the middle?

Answer 3

well so is the axis of symmetry

Answer 4

y=ax^2 +bx +c
y=3x^2+7x-4

Answer 5

a = ??

Answer 6

2

Answer 7

no no! remember from the last one. What number is in the place of a?

Answer 8

y=ax^2 +bx +c
y=3x^2+7x-4

Answer 9

3

Answer 10

yes!
a = 3

Answer 11

b =??

Answer 12

b=7?

Answer 13

yep!

Answer 14

a= 3
b=7

Answer 15

so its a?

Answer 16

nope

Answer 17

heres your graph:

Answer 18

they want this line

Answer 19

but the cool thig is it passes throught the vertex just like the last one
