(Brainliest) Find the equation of the graph, at what values of x does the graph reach its maximum values, on what intervals is the graph increasing, is this function odd or even or neither.

Answer:
Step-by-step explanation:
The max value that this function reaches is 6, and the function reaches this value repeatedly, beginning at x = 0 and then at x = 6, 12, 15, etc. Â This tells us that the period of the function is 6. Â
The function is increasing on (3, 6), (9, 12), and so on
The function is even because the graph is symmetrical about the y-axis.
