Question

Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
f(x) = 6 cos x ; g(x) = cos x

Answer 1

nothing happens to the periodicity, but the amplitude of the curve increases by 6 times.

Answer 2

Vertical stretch by a factor of 6 **this one ?

Horizontal shrink by a factor of one-sixth

Horizontal stretch by a factor of 6

Vertical shrink by a factor of one-sixth

Answer 3

it's just stretching the graph vertically by factor of 6.
a is the answer.

Answer 4

thank you (:

Answer 5
