The number of bacteria in refrigerated food is given by N (T) = 20T2-20T + 120, for -2 ≤ T ≤ 14, and where T is the temperature of the food in Celsius. At what temperature will the number of bacteria be minimal?

240

Step-by-step explanation:

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
