Question

Find the constant of variation for the relationship f(x)= 30x.

A.


10


B.


30


C.


x


D.


f(x)

Answer 1

I believe the correct answer from the choices listed above is option B. The constant for variation of the relationship f(x)=30x would be 30. The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.

Answer 2

For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.
