Question

Which of the following shows a positive nonlinear ​relationship? ​ (assume values of x greater than 0​) A. y equals 5 plus StartRoot x EndRoot B. y equals 5 plus 7.2 x C. y equals StartFraction 86 Over x EndFraction D. y equals 86 minus 6.6 x Click to select your answer.

Answer 1

A and C represent positive nonlinear relationships

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=
`(1)/(x)` is a non linear relationship and x≥0 then y=
`(86)/(x)` is positive and nonlinear.
