I After Olivia timed herself for 30 days, she determined her average time in seconds to refuel an IndyCar, is equal to the function f(g), where f(g) = 2.2g, where g is the number of gallons needed to fill an Indy car. HIMA a. What is the value of f (g) at f(21)? (1/2 point) seconds b. Based on the context, which statement is true. Select One.
