Answer:
B
Step-by-step explanation:
So, a function is increasing when the y-values increase with the x-values. Ok?
So, A is constant, because while the x-values are increasing, the y-values aren't changing at all.
B is increasing because both the x and y values are increasing.
C is once again constant, for the same reason as A.
D is decreasing because as x-values increase, y-value decrease.
