Question

Which of the following has the values of its range increase as the values in its domain increase?(1 point)
Responses

y=−2x−4

y is equal to negative 2 x minus 4

y=4

y is equal to 4

y=3x+1

y is equal to 3 x plus 1

y=−12x+3

Answer 1

y = 3x + 1

Reason: For a linear function y = mx + b, y increases as x increases exactly when the slope m > 0. Here m = 3 > 0, so the range increases as the domain increases.
