Question

Select the equation that is a rational function

A. y=x
B. y=x/(x+3)
C. y=x^3
D. y=2^x

Answer 1

y = x/x+3 is a rational function

Explanation:

Here, we want to select the equation that is a rational function

rational functions are such that could be expressed as the division of one function by another

For example;

f(x) = g(x)/h(x)

is a rational function

so, if we applied this here,

we have it that;

y = x/x+ 3 is a rational function
