For this case, we have a function of the form y = f (x) , where f (x) = 7x-5

You want to know the value of the given function when x = 2 ,

Then we substitute x = 2 in the function:

$f (2) = 7 (2) -5\\f (2) = 14-5\\f (2) = 9$

So, the value of the function is 9 when x = 2

f (2) = 9

Inverse variation is of the form yx=k, we are given the point (0.2, 100) so we can solve for k, the constant of variation...

0.2(100)=k

20=k
