Question

What would a cosine function look like with a given amplitude of 7, period of pi/6, no horizontal shift, and vertical shift of down 2?
Hint: f(x)=a cos(bx+c)+d

I need help

anonymous · Answer

a is the amplitude; b is (2pi)/period; c is the horizontal shift; and d is the vertical shift.

anonymous · Answer

So the formula is f(x)=7cos(pi/6+c)-2? @marshallinwashington

anonymous · Answer

Close, but you need to figure out the b value. We are given that there is no horizontal shift, so c=0.

The b value is (2pi)/period. We are given the value for the period.
