Respuesta :
the missing value (3,7),(8, y) is y = 21/8
What exactly is a function's inverse?
Inverse functions are those that cancel one another out. In other words, if g(x) is f's inverse, then f(g(x)) = g(f(x)) = x. (x). Given an equation for which we want the inverse, we have a fantastic method we can utilize to do this.
Not every function has a counterpart. If f(x) has an inverse, it is clear to see that it will never again have the same value. We give this resource a special name.
Inverse variation is y = k. 1/x
given y = 7
x = 3
So, 7 = k. 1/3
So, the value of k = 21
We can conclude that the value of constant variation is 21
when x = 8, the value of y will be -
y = k.1/x
y = 21 . 1/8
y = 21/8
