Functions can either be discrete or continuous.
The function is given as:
[tex]\mathbf{y = 35x}[/tex]
Where x represents the number of blankets
x can only take whole numbers (i.e 0, 1, 2....)
A discrete function is such that can only non-decimal values.
Hence, the function is discrete
(b) The domain
In (a), we listed the values of x to be: (0,1,2...)
This means that, the domain is: [tex]\mathbf{[0,\infty)}[/tex]
(c) The range
When x = 0, we have:
[tex]\mathbf{y = 35x}[/tex]
[tex]\mathbf{y = 35 \times 0 = 0}[/tex]
This means that, the range is: [tex]\mathbf{[0,\infty)}[/tex]
