Which of the following statements is true of all linear functions? Range: {all real numbers} Always increasing Discrete Domain: {all real numbers}

Options (1) and (4)

Step-by-step explanation:

Linear functions are the functions represented by a straight line either increasing or decreasing.

Domain and Range of the function is represented by the x-values (input values)and y-values (output values).

Since a linear function is always continuous, domain is a set of all real numbers (x-values on x-axis) and Range is the a set of all real numbers (on y-axis).

Discrete function can have limited values on the graph so the linear graph can't be a discrete function.

Options (1) and (4) are the correct options.
