Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g( f(x) = 9 cos x ; g(x) = cos x choices: a) horizontal stretch by a factor of 9

b) vertical stretch by a factor of 9

c) horizontal shrink by a factor of one-ninth

d) vertical shrink by a factor of one-ninth

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

what?

what do you need with. i love quadrants. can you tell me ?
