Question 547090
describe the relationship between the graphs of f and g ? 
1.f(x) = cos x
g(x) = cos (x + pi)
curve of f shifted π radians to the left
.. 
2. f(x) = sin x
g(x) = sin 3x
Amplitude of f increased by a factor of 3
..
3. f(x) = cos 4x
g(x) = -2 + cos 4x
Curve of f dropped vertically by 2 units
