Question

Consider the functions:
f(x) = −2 cos x
g(x) = −2 cos(x −1/2π)
Which statement best describes the relationship between the graphs of f(x) and g(x)?
1. g is a vertical shift of f upward by
1/2πunits.
2. g is a horizontal shift of f to the left by
1/2π units.
3. None of these
4. g is a vertical shift of f downward by
1/2πunits.
5. g is a horizontal shift of f to the right by
1/2π unit

Answer 1

#4

Answer 2

it says that its wrong :/

Answer 3

oh of course it is i am sorry

Answer 4

f(x) vs f(x+p) is a HORIZONTAL SHIFT not vertical. my fault

Answer 5

horizontal shift to the right in this case

Answer 6

so it would be #5?
