Rational Function Cart Speed Q7

Determine cart speed and time for Anita.
Reciprocal function of f(x) is 1/f(x). Denominator cannot be zero; that leads to restrictions. Reciprocal function graph will be discussed in details along with word problems. Rate related questions are good to model with reciprocal functions.
Rational functions are quotient of polynomials. All reciprocal functions are not rational functions.
Do you know when will there be a vertical asymptote and when will there be a hole? We will explore these parameters along with simplification to equivalent expressions and other operations.
