You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.
8 = 4 * 2
You can take the square root of 4 and put it outside the root.
18 = 9 * 2
You can take the square root of 9 and put it outside the root.




In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)

Answer:
1.
2.
and 
3. 
Example: 
Step-by-step explanation:
1. We have
, and we have to prove that this term is equivalent to
.
Now,
=
{Since we know the property of exponent as
}
=
=
2.
and
3. The power of products property gives
........ (1)
For example, we can write, 
1. One value of x for f(x)=-4 would be 0.
2. Should be 3.5 and -3.5 but I'm not sure
