Tanya runs a catering business. Based on her records, her weekly profit can be approximated by the function f(x) = x2 + 2x - 37, where x is the number of meals she caters. If f(x) is negative, it means that the business has lost money. What is the least number of meals that Tanya needs to cater in order to have a profit?

Respuesta :

Answer:

5

Step-by-step explanation:

f(x) = x2 + 2x - 37

using x=(-b±√(b^2-4ac))/2a

x=(-2±√(2^2-4(1)(-37))/2(1))

x= -7.164 or 5.164

to gain profit she has to cater 5 meals
