SOLUTION: please help me figure out the rest of this equation. i have done the first step but am confused on how to place/write out the sine function with amplitude of 4, period of pi, and y

Question 690908: please help me figure out the rest of this equation. i have done the first step but am confused on how to place/write out the sine function with amplitude of 4, period of pi, and y-intercept of -3
I only have y=4sin
I would greatly appreciate your help and time, thank you.

sine function with amplitude of 4, period of pi, and y-intercept of -3
------
y = asin(bx)+c
a = |4| = 4
---
Since period = 2(pi)/b = pi
b = 2
---
y-int = a*sin(b*0)+c = -3
a*0+c = -3
c = -3
---------------------
Equation:
y = 4sin(2x)-3
