[4 over x equals 5 over 10]
Solve for x, so you need to isolate/get x by itself in the equation.
Multiply x on both sides

Multiply the inverse of 5/10, which is 10/5, to get rid of the fraction and get x by itself

Answer:

Step-by-step explanation:
Three pairs are given completely:
(x, f(x)) = (1, 1), (49, 7), (25, 5)
We observe that this is not a linear relation. Rather, squaring the f(x)-value gives the x-value.
f(x)^2 = x
f(x) = √x
