Since this is a linear function, filling in the minimum and maximum of the domain is sufficient.
f(-4) = -16 + 9 = -7
f(2)= 8 + 9 = 17
So the range of the function (given the domain) :
R = {-7, 17}
So firstly, square root 9a^2 and 49: 
Next, combine like terms, and your answer will be
, or the third option.
<h2><u>Quadrilateral</u></h2>
<h3>Classify the quadrilateral in as many ways as possible.</h3>
Shown in the figure, all the measurements of each sides is different, so it is only a quadrilateral. Square has four equal sides and angles, rhombus has only four equal sides, and a parallelogram whose opposite sides are parallel.
<u>Answer:</u>
<em>Picture 1 (Rhombus)</em>
<em>Picture </em><em>2</em><em> </em><em>(Square)</em>
<em>Picture 3 (Parallelogram)</em>
<em>Picture 4 (Quadrilateral)</em>
