  3(n+4) = 12

Step-by-step explanation:

The sum of n and 4 is (n+4). Three times that sum is 3(n+4). When we say it "is 12", we mean it is equal to 12.

  3(n +4) = 12

Compared to a standard cosine function, the graph has a phase shift of to the right, and compared to a sine function it has a phase of shift of to the right.

Step-by-step explanation:

The standard cosine function has its maximum (vertex of the interval concave down) intersect with the y-axis. In this case, that part is shifted to the right.

The standard sine function has the point where it crosses its midline intersect with the x-axis. In this case, that part is shifted to the right.
