Question

What is the axis of symmetry for the function? y = x2 + 3x - 4

Answers:

a) y = -2

b) y = -1.5

c) x = -2

d) x = -1.5

Answer 1

hint:

Axis of Symmetry for y = ax^2 + bx + c is

x = -b/(2a)

Answer 2

O.o i don't get it D:

Answer 3

what are a, b and c in this case?

Answer 4

x2, 3x, -4

Answer 5

i think...

Answer 6

a, b, and c are the numbers without the variables

Answer 7

so,

a = 1
b = 3
c = -4

Answer 8

oh, okay

Answer 9

so what is x = -b/(2a)

Answer 10

-3/(2*1)

Answer 11

keep going

Answer 12

that for sure wrong

Answer 13

nope it's correct, keep going

Answer 14

you're doubting yourself for no reason

Answer 15

I think it would equal -1

Answer 16

because -3 divided by 3 = -1

Answer 17

no, it's not -3/3 it's -3/2 = ???

Answer 18

omg 2*1 im stupid lol

Answer 19

nah you're not, silly typo

Answer 20

-1.5 then

Answer 21

yep you got it

Answer 22

so x = -1.5

Answer 23

:O

Answer 24

thanks!

Answer 25
