Choose the correct classification for each of the graphs. Select each correct answer.

Options: 

Even function

Odd function 

Both Even and Odd function

Neither Even or Odd function

 

Graphs:

A cosine function graphed on a coordinate plane. The horizontal x-axis ranges from negative 3 pi to 3 pi in increments of pi over 2. The vertical y-axis ranges from negative 10 to 10 in increments of 2. The function begins at begin ordered pair negative 3 pi comma negative 6 end ordered pair and increases in increments of pi over 2 until reaching begin ordered pair 3 pi comma negative 6 end ordered pair. The function begins at begin ordered pair negative 3 pi comma negative 6 end ordered pair and increases to a maximum value of begin ordered pair negative 2 pi comma 6 end ordered pair. The graph then decreases to a minimum value of begin ordered pair negative pi comma negative 6 end ordered pair and increases to a maximum value of begin ordered pair 0 comma 6 end ordered pair. The graph then decreases to a minimum value of begin ordered pair pi comma negative 6 end ordered pair and increases to a maximum value of begin ordered pair 2 pi comma 6 end ordered pair. The graph then decreases to a minimum value of begin ordered pair 3 pi comma negative 6 end ordered pair.

A parabola graphed on a coordinate plane. The horizontal x-axis ranges from negative 10 to 10 in increments of 2. The vertical y-axis ranges from negative 10 to 10 in increments of 2. The vertex is located at begin ordered pair 0 comma negative 9 end ordered pair. The parabola opens upward. It passes through the horizontal axis at begin ordered pair negative 3 comma 0 end ordered pair and begin ordered pair 3 comma 0 end ordered pair.

The first graph is the graph of      y  =   6cos(x)

 

This graph is symmetric about the y axis....so it is even

 

 

 

The second graph  is the grah  of  y  = x^2  - 9

It is also symmetric about the y axis....so  it is also even
