Answer provided by our tutors
The equation that represents the height as a function of the time is:
f(x) = 34 + 2.625x, where x represent the amount of year since age 2
We need to find x such that f(x) = 50 that is:
34 + 2.625x = 50

x = 6 years rounded to integer
6 years after the age of 2 is 2 + 6 = 8 years.
Monique's son will be 8 years old and 50 inches tall.
