Answer:
f(x)^-1=
-1
f(x)=x^3+1+3x^2+3x
Step-by-step explanation:
Answer:
1. y = sin(x²+C)
2. see below
Step-by-step explanation:
1. 
separation of variables

integration both sides
you should get :
remember constant of integration!!
2. y = sin(x²+C)
3 = sin(0+C)
y(0) = 3 does not have a solution because our sin graph is not shifted vertically or multiplied by a factor whose absolute value is greater than 1, so our range is [-1,1] and 3 is not part of this range
