Which graph represents the function y = –2cos(2πx)?
On a coordinate plane, a function has a maximum of 2 and minimum of negative 2. It completes one period at StartFraction 2.5 pi Over 4 EndFraction. It crosses the y-axis at (0, negative 2).
On a coordinate plane, a function has a maximum of 2 and minimum of 2. It completes one period at one-fourth pi. It crosses the y-axis at (0, negative 2).
On a coordinate plane, a function has a maximum of 2 and minimum of 2. It completes one period between StartFraction pi Over 2 EndFraction and StartFraction 3 pi Over 4 EndFraction. It decreases through the y-axis at (0, 0).
