a.f(x) = 7 sin 8x + 3
b .f(x) = 3 sin 8x + 7
c.f(x) = 7 sin( pi/4 x)+3
d.f(x) = 3 sin(pi/4x) + 7

(1) Which of the following would best represent a sine function with an amplitude of 7, a period of pi/4 , and a midline at y = 3
I have been stuck on this and 2 more for 2 days skipping over it can I get help please and steps of how to do it
