Q:

What is the domain of f(x) = 3x – 2?{x | x > 0} {x | x < 0} {x | x = 0} {x | x is a real number}

Accepted Solution

A:
Answer: las option.Step-by-step explanation: The equation of the line in slope-intercept form is: [tex]y=mx+b[/tex] Where m is the slope of the line and b is the y-intercept. Then function given in the problem has the form: [tex]f(x)=3x-2[/tex] Where: m=3 b=-2 Therefore, it is a linear function. By definition, the domain of the  linear functions that are not bounded, is all the Real numbers. Therefore, the answer is: {x | x is a real number}
