The correct options include B "The sine function rises in the intervals (0°, 90°) and (270°, 360°)." E "Both sinusoidal functions reach a peak value of 1." and F "Both functions exhibit periodic behavior."
Regarding the logarithmic equation, option c is correct: x=6 is a valid solution, while x=-6 is considered an extraneous solution. Explanation: The equation requires dividing both sides by 2, simplifying further until each step can be logically followed based on logarithmic definitions, from which we affirm that both sides equal when substituting back the values, confirming that x=6 is the true solution.
