59. For a specific nonzero value of b, the graph of y = sin bx in the standard (x, y) coordinate plane intersects the x-axis at k values of x in the interval 0 ≤ x ＜ 2π. At how many values of x in this interval does the graph of y = 2 sin bx intersect the x-axis?

Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

Because only the amplitude changes and the frequency does not change, so the number of intersections with the x-axis remains the same, so A is selected for k
