Rational functions are functions written as fractions. According to the question, we are to select the function for which as y tends to minus infinity, x will tend to positive infinity.
For the function
y = -√x - 6
Substitute y = -∞ into the equation
- ∞ = - √x - 6
x - 6 = ∞
x = ∞ + 6
x = ∞
Therefore Rational functions are functions written as fractions. The correct function is y = -√x - 6
