Solution

To identify: The equation of the graph.

The option (D) is the right answer.

Given data: The graph of one of the following equation is shown in Fig. 1. The right equation is,

  A  y=−3cos2x                 B y=−2cos3xC  y=−12cos3x               D y=−3cos12x

  Mcdougal Littell Algebra 2: Student Edition (c) 2004 2004, Chapter 10, Problem 4TP

Method/Formula used:

Find the given points satisfy which one of the given equations.

Calculations:

The point 0,−3 lies on the graph. Verify to which equation the point 0,−3 satisfies.

Equation (A):

Substitute 0 for x and -3 for y in equation (A),

  −3=−3cos20=−3cos0=−3

The point 0,−3 satisfies equation y=−3cos2x , therefore, the equation y=−3cos2x may be an equation of the given graph.

Check with another point 2π,3 :

Substitute 2π for x and 3 for y in equation (A),

  3=−3cos2π=−3⋅1              ←cos2π=1=−3

The point 2π,3 does not satisfy equation y=−3cos2x , therefore, the equation y=−3cos2x is not an equation of the given graph.

Equation (B):

Substitute 0 for x and -3 for y in equation (B),

  −3=−2cos0⋅x=−2cos0=−2⋅1=−2

The point 0,−3 does not satisfy equation y=−2cos3x , therefore, the equation y=−2cos3x is not an equation of the given graph.

Equation (C):

Substitute 0 for x and -3 for y in equation (C),

    −3=−12cos30−3=−12cos0=−12⋅1−3=−12

The point 0,−3 does not satisfy equation   y=−12cos3x    , therefore, the equation   y=−12cos3x    is not an equation of the given graph.

Equation (D):

Substitute 0 for x and -3 for y in equation (D),

  −3=−3cos120−3=−3cos120=−3⋅1=−3

The point 0,−3 satisfies equation y=−3cos12x , therefore, the equation y=−3cos12x may be an equation of the given graph.

Check with another point 2π,3 :

Substitute 2π for x and 3 for y in equation (A),

  3=−3cos122π=−3cosπ              ←cosπ=−1=−3−1=3

The point 2π,3 satisfies equation y=−3cos12x , therefore, the equation y=−3cos12x is an equation of the given graph.

Since, two points 0,−3 and 2π,3 satisfy the equation y=−3cos12x .

Therefore, equation y=−3cos12x is the right equation of the given graph.

Thus, option (D) is the right answer.
