F(x)=3 domain: negative infinity, positive infinity range: 3
g(x)=x+7 domain: - infinity, + infinity range: - infinity, + infinity
It is C. r=6
3 * 6 = 18 + 2 =20
Answer:


Step-by-step explanation:
We are given that

y(0)=-1


Taking integration on both sides then we get


Using formula


Substitute x=0 and y=-1



Substitute the value of C



By using quadratic formula


Hence, the solution 
When the solution is maximum then y'=0







The answer is
x _ 2y = 2
<span>3x + y = 6
</span>3x _ 6y = 6 (1
<span>3x + y = 6 (2
</span>(1 - (2
-7y=0, y=0, so x - 2.0=2 implies x=2
