The domain of the function is the value of the independent variable, or simply the x-values. The range is the value of the dependent variable, or the y-values. You can determine its domain and range if the curve of the function passes through their coordinates. Hence,

A. True. If you extend the curve downwards, its opening widens and would then encompass all x-values
B. True.
C. False. This is contradictory to A.
D. True. This is same with B.
E. False. This is contradictory to B.
F. False, the origin is at (0,2). It does not extend upward.

The answers are A, B and D.

Please help!! (Number 73)

So hmm notice the picture below

one is 7x5x1.75 the volume of a rectangular prism is V = length * width * height

so 7*5*1.75 gives us 61.25 ft³

the second one, is larger by some width and length we dunno, but we know that it required that 61.25 plus an extra 17.5 to fill it up, so its volume is 61.25 + 17.5 or 78.75

the height is the same... so $\bf V=l\cdot w\cdot h\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\ --------\\
h=1.75\\
V=78.75
\end{cases}\implies 78.75=lw\cdot 1.75
\\\\\\
\cfrac{78.75}{1.75}=lw\implies 45=lw$

so.. if you factor 45, to two factors, one will be the length, the other the width
