I hope this helps - it depends what you doing for it to be negative or nonnegative.. :)
Answer:
f+g(2)=10
f-g(4)=-4
F/G(2)= 7/3
(f)(g)(1)=0
Step-by-step explanation:
1. (f+g)=2x+3+x^2-1 2(2)+2=10
2. (f-g)=(2x+3)-(x^2-1)=-x^2+2x+4= -16+8+4=-4
3. f/g= 2x+3/x^2-1 4+3/3= 7/3
4. f*g= (2x+3)(x^2-1)= 2x^3+3x^2-2x-3= 2(1)^3-2(1)+3(1)^2-3=0
Answer: 1610
Step-by-Step Explanation:
Lets round off each number,
=> 23.4 to 23
=> 13.9 to 14
=> 0.18 to 0.2
Therefore,
= 23 * 14 / 0.2
= 322 / 0.2
= 1610
