Explanation / Answer

a) f(x) = 1.4 cos ( 0.6 (x - 3) ) + 4

i) period of the function is 2pi/ 0.6 = 10pi /3 = 10.47

ii) minimum value of f is 2.6

iii) maximum value of f is 5.4

iv) amplitude of the function is 1.4

2) f(x) = 1.6 sin ( 6pi x - 0.6 ) - 9

i) period of the function is 1/3

ii) minimum value of f is -10.6

iii) maximum value of f is -7.4

iv) amplitude = 1.6
