2. Graphing a cosine function using five key points. (24 points) y = cos -2x+ 4T 3 +3 1) Use the even/odd property to rewrite the function in an equivalent form in which the coefficient of x in the argument is positive (3 points) 2) State the amplitude (1 point) 3) State the period (2 points) 4) State the phase shift (2 points) 5) State the domain (1 point) (2 point) 6) State the range. 7) Find the x-coordinates of the five key points (complete the chart): (3 points) 7) Find the x-coordinator of the five lev
