What is the axis of symmetry of h(x) = –2x2 + 12x – 3?

h(x) = -2x2 + 12x - 3?

The axis of symmetry is :

x = 3

Hope this helps.

The axis of symmetry at x= 3asdfsdf

Step-by-step explanation:

the axis of symmetry of

To find axis of symmetry we apply formula

Given equation is in the form of ax^2 + bx+c

a= -2 and b= 12

Plug in the values in the formula

The axis of symmetry at x= 3

3/6   and 9/18

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
