The given function is
We need to find the number of hours does the quality control facility operate each day.
Rewrite the given function it factored form.
Taking out the common factors from each parenthesis.
The factored form of given function is c(t)=-(t-10)(t+2).
Equate the function equal to 0 to find the x-intercept.
Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

Answer:
The function given is non-linear.
Step-by-step explanation:
The slope between (0, 2) and (2,6):
The slope between (2,6), and (3, 12):
Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.
