Answer:

A and C represent positive nonlinear relationships

Step-by-step explanation:

We assume that x≥0

A. Since √x is positive and nonlinear because the exponent of x is 1/2, then y=5+√x is always positive and is nonlinear.

C. Since x^-1=[tex]\frac{1}{x}[/tex] is a non linear relationship and x≥0 then y=[tex]\frac{86}{x}[/tex] is positive and nonlinear.
