What is the amplitude of the function y = a sin(bx)?

Back

The amplitude is the absolute value of 'a' in the function, which represents the maximum distance from the midline.

How do you determine the vertical shift of a cosine function?

Back

The vertical shift is determined by the constant added or subtracted from the function, represented as y = a cos(bx) + d, where d is the vertical shift.

What does a phase shift refer to in trigonometric functions?

Back

A phase shift refers to the horizontal shift of the graph, which can be left or right, determined by the value of c in y = a cos(b(x - c)).
