Answer:
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.
