Question

What sine function represents an amplitude of 4, a period of pi over 2, no horizontal shift, and a vertical shift of −3?

Answer 1

f(x) = −3 sin 4x + 4

f(x) = 4 sin 4x − 3

f(x) = 4 sin pi over 2x − 3

f(x) = −3 sin pi over 2x + 4

Answer 3

its the 2nd option

Answer 4

The general form is f(x) = Asin(Bx + C) + D (like we did the previous question)
Amplitide A = 4
Period = 2*pi / B = pi / 2. Solve for B
Phase shift = 0 implies C = 0
Vertical shift D = -3.
Plug it into the equation above.

Answer 5

alright thank you i'll do that :) x
