Function that models each inverse variation is y = 50.1/x and find y when x=-5 will be -10.
A function model or functional representation is an organized depiction of the functions (activities, actions, processes, and operations) inside the modeled system or subject area.
Inverse variation formula is y = k. 1/x
⇒ for x = 25 and y = 2,
The value of k will be -
k = y . x
k = 25 . 2
k = 50
⇒ y = 50 . 1/x is our function
⇒ for x = -5,
⇒ y = 50 / -5
⇒y = -10
