[tex]y = 650x[/tex] is an illustration of a linear function

  • The domain of the function is: [tex][0, \infty)[/tex].
  • The domain is continuous

The function is given as:

[tex]y = 650x[/tex]

Where:

[tex]x \to[/tex] hours on the clock

Because x represents time, it cannot take a negative number.

So, the domain is [tex]x \ge 0[/tex] or [tex][0,\infty)[/tex]

Also:

x can take a whole number or decimal numbers

i.e. You can climb for 1 hour, 2 hours or part of an hour

When a data can take decimal, then such data is continuous.

Hence, the domain is continuous
