What is the function that matches the description.
A sinusoidal function has a y-intercept at 3, midline y = 3, and maximum value of 6 and completes 3 cycles in the interval [0,2π]
sinx x and cosx normally have midline = 0 this one is shifted UP 3 units so it needs a +3 at the end....
all of these fit that req
y intercept at 3 means it is a sin function which normally has 0 as y-axis intercept...it is shifted up 3
3 cycles in 2 pi means the function of x is sped up three times sin (3x) (normally cycle is 1 time per 2 pi)
sin (3x) + 3
max value of 6 means it has been multiplied by 3 usually max value is 1 multiplied by 3 then equals3 then shifted up 3 = max value 6
3 sin(3x) + 3
