Answer: Option d.
Step-by-step explanation:
To find the domain of the function we should look for the values for which the denominator is equal to zero, because the division by zero is not allowed.
We know by definition that the function 
is always greater than zero for all <em>x</em>.
We know that the constant <em>c</em> is greater than zero (c>0).
Then, the expression 
is never equal to zero.
Therefore, it does not exist a value for <em>x</em> that makes the denominator 0. Then, the domain of the function is all real numbers.
The answer is the option d.

"The given statement is true, by definition of length of a vector 
, 
"
Step-by-step explanation:
(a) 
That is completely correct Remember that if 
then
Therefore the correct answer would be (c).
"The given statement is true, by definition of length of a vector , "
Below are the choices:
<span>-1/2
0
-1
non
</span>
The exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution,
<span>4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2</span>
