Periodic Phenomena Practice Test

The average monthly temperature in a city is modeled by a periodic function, $$T(m)$$, where $$m$$ is the month number. The function has a period of 12 months. The function is increasing from $$m=1$$ (January) to $$m=7$$ (July).

Let $$g(t)$$ be a periodic function with a period of 6. A minimum value of the function occurs at $$t=2$$.
