the value of a is 2 bc by looking at the graph a normal parabola of x^2 would bc followinf the 1-3-5 rule but this does not

from the vertex it goes over 1 and up 2

Lets write it in vertex form

y = a(x - 1)^2 - 2        (because the vertex is at (1, -2)

Now the zeroes are   0 and 2 so substituting x = 2 and y = 0 in the above:-

0 = a(2-1)^2 - 2

0 = a - 2

a = 2

so we have y = 2(x - 1)^2 - 2

which in standard form is  

y = 2x^2 - 4x + 2 - 2

y = 2x^2 - 4x   is the answer

If x=-6, which inequality is true ??<br>​
Gelneren [198K]

<em>Answer:</em>

The inequality that is true is -5 - 3x > 10.

<em>Step-by-step explanation:</em>

if x = -6

we can subtitution x to every inequality, so :

-5 - 3x > 10

-5 - 3(-6) > 10

-5 - (-18) > 10

-5 + 18 > 10

13 > 10 [true]

-3 - 5x < -14

-3 - 5(-6) < -14

-3 - (-30) < -14

-3 + 30 < -14

27 < -14 [false]

2 - x < -3

2 - (-6) < -3

2 + 6 < -3

8 < -3 [false]

So if x=-6, inequality true is -5 - 3x > 10.
