Answer:
y=(1/6)x.
Explanation:
A linear function is a function in which the the highest power of the variable is 1.
• In option A, the highest power of the variable s is 3. Therefore, it is a cubic function.
,
• In Option C, the variable is an exponent, therefore, it is an exponential function.
,
• In option D, the highest power of the variable r is 2. Therefore, it is a quadratic function.
However, in Option B, the highest power of x is 1. Therefore, the equation that describes a linear function is y=(1/6)x.
