The domain of the function is all values of x that make the function defined
The range of the function is the values of y corresponding to x
Since the given equation is
[tex]y=350x+1500[/tex]Since x represents the number of months, then
x should be a positive number
Then
[tex]x\ge0[/tex]The domain of the function is
[tex]x\ge0[/tex]To find the range substitute x in the equation by 0 (first value)
