The given compound inequality in Interval Notation is

 -2 < x ≤9

From left side the notation is , semi open(either < or >) and from right side the interval notation is closed(either ≤ or ≥).

So, it can be represented as→(-2,9]

Option C→(−2,9]

-2 < x <= 9.....use [ ] when there is an equal sign....use ( ) when there is not an equal sign.

(2 , 9 ] ....greater then 2, less then or equal to 9

Find an expression for the area enclosed by quadrilateral ABCD below.
Helga [31]
  • ∆ABD is right angled hence area:-

\\ \sf\longmapsto \dfrac{1}{2}bh

\\ \sf\longmapsto \dfrac{1}{2}(4x)(3x)

\\ \sf\longmapsto \dfrac{1}{2}(12x^2)

\\ \sf\longmapsto 6x^2

There is only one option containing 6x^2 i.e Option D.

Hence without calculating further

Option D is correct

For a translation of 4 units right, the graph will become -3(x-4). the 4 is negative to indicate that the translation is right.
For a vertical stretch of 4, the graph will become 4x-3(x-4)=-12(x-4). 

With this information, g(x)=-12(x-4)
