Answer:
[tex]w \ne0[/tex]
Step-by-step explanation:
The area of a rectangle is given by:
[tex]Area = L \times \: W[/tex]
In this case, we have the height replacing the length.
[tex]Area=H\times w[/tex]
The area of the rectangle is 70.
[tex]H\times w = 70[/tex]
Dividing through by w gives:
[tex]H = \frac{70}{w} [/tex]
Or to show that H is dependent on w, we write
[tex]H (w)= \frac{70}{w} [/tex]
[tex]w \ne \: 0[/tex]
Domain is the set of all real numbers for which the function is defined.
Therefore the domain is all real numbers except 0.
