You have to make the fraction into an integer. the simplest version of a ratio involves the smallest possible integers. therefore, 5:2.5 will equal 10:5 (you multiply both sides by 2). 10:5 cancels down to 2:1. hope this helped :)

Which represents the inverse of the function f(x) = 4x?
nekit [7.7K]

Answer:

\displaystyle h(x) = \frac{1}{4}x

Step-by-step explanation:

Sinse in this case you are dealing with direct variation, all you are doing is taking the <em>multiplicative</em><em> </em><em>inverse</em><em> </em>of 4, which is ¼:

\displaystyle f(x) = 4x \rightarrow f^{-1}(x) = \frac{1}{4}x

This option is not an answer choise. Perhaps there was a typographical errour.

I am joyous to assist you at any time.
