Increasing `A,` while keeping the other constants the same, moves the graph of `f` up. Similarly, decreasing the value of `A` moves the graph of `f` down.
Large values of `B` correspond to large oscillations in the graph of `f`. Small values of `B` correspond to small oscillations.
Changing the sign of `B` reflects the graph of `f` about the line `y=A.`
Increasing the value of `D` moves the graph of `f` to the right.
Increasing the value of `C` increases the frequency of the oscillations and decreases the period.
