The velocity V(x) = `(350*x)/(1+x^2)^(3/4)` where x is defined in terms of 10000 light years. The limiting form of V(x) has to be determined. This means the value of V(x) has to be determined for values of x as it takes on very small values or tends to 0 and as it takes on very large values or tends towards infinity.
Looking at the velocity function V(x) it is seen that as x tends to 0, the numerator 350*x tends to 0 and the denominator tends to 1. The value of V(x) therefore tends to 0.
V(x) can be written as `350/((1/x^(4/3) + x^(3/2))^(3/4))`
As x tends to infinity the value of 1/x^(4/3) tends to 0 and the value of x^(3/2) tends to infinity, the sum of the terms that form the denominator tends to infinity. If the denominator of a fraction tends to infinity, the fraction tends to 0.
V(x) tends to 0 both for values of x that tend to 0 and for values of x that tend to infinity.
