Question

For a sinusoidal function in the form y = A sin Bx + C or
y = A cos Bx + C, the period is 1, the minimum is negative 7, the equation of the midline is y = minus 2, the y-intercept is 3, and A > 0.

What is the equation of the function?

y = 5 sin (2pi x) minus 2
y = 9 sin (2pi x) minus 2
y = 5 cos (2pi x) minus 2
y = 9 cos (2pi x) minus 2

Answer 1

I AM SEEING DIAMONDS???

Answer 2

�������������

Answer 3

idk why that literally just happened when i added you

Answer 4

still seeing diamonds lol

Answer 5

I can see till period is 1

Answer 6

the minus sign is making the diamonds appear

Answer 7

HI!!

Answer 8

they all have period 1 since \(\frac{2\pi}{2\pi}=1\)

Answer 9

misty can you see the question??

Answer 10

the minimum of sine and cosine is -1, so choose one that has a 5 at the front and a \(-2\) at the end

Answer 11

now we're talking

Answer 12

we have narrowed it down to A and C

Answer 13

y intercept is three

Answer 14

i see

Answer 15

substitue x=0 and check in which y=3

Answer 16

the ans that gives you y=3 is the one

Answer 17

yes

Answer 18

easy peesy Japaneesy

Answer 19

can you now tell whats the ans??...A/B/C/D?? try
