Question

Which function describes the graph shown below?

On a coordinate plane, a curve crosses the y-axis at (0, negative 2), increases to negative 2.5, decreases to negative 2.5, and then increases again.
y = one-half sine (x) minus 2
y = 2 sine (x) minus one-half
y = one-half cosine (x) minus 2
y = 2 cosine (x) minus one-half

Answer 2

The function shown by the graph is a sine function give. as: y = one-half sine (x) minus 2.

What is the graph of a sine function?

The graph of a sine function has and up-down curve that repeats every 2π radians, or 360°.

The graph starts at 0, heads up to 1 by π/2 radians or 90° and then heads down to −1.

The given graph of the function crosses the y-axis at (0, negative 2), increases to negative 2.5, decreases to negative 2.5, and then increases again.

Therefore, the function shown by the graph is the sine function; y = one-half sine (x) minus 2.
