Question

Does the function show a direct linear variation, quadratic variation, or inverse variation? Explain. A. f(x) = 1/8x^2 B. xy=9 C. p(x)=x/11

Answer 1

A shows direct quadratic, B shows inverse and C shows direct linear

Explanation:

A is the form of y=k*x^2 which is direct quadratic

B is the form y*x=k which is not direct means it is inverse

C is the form y=k*x which is direct linear variation

Note: k is any constant.
