A sinusodial function whose frequency is 3, maximum value is 12, minimum value is -6 has a y-intercept of 3. What function could be the function described

f(x)=9sin(6πx)+3

1. x = 66

2. C

3. C. 2000

Step-by-step explanation:

1. The first question is x = 66 because to get rid on the fraction you multiply both sides by 4. This leaves you with x + 2 = 68 (minus 2 on both sides) this gives you x = 66.

2. C. Commutative

3. 2000

Plug in

125 = (5)(.0125)(2000)

125 = 125

Hope this helps ya!!
