Answer:
x ≥ -1/2
Step-by-step explanation:
We know that we cannot graph imaginary numbers. Therefore, our <em>x </em>value has to be greater than or equal to 0:
To find our domain, we need to set the square root equal to zero:
√(4x + 2) = 0
4x + 2 = 0
4x = -2
x = -1/2
We now know that no value below -1/2 can be used or we will get an imaginary number. Therefore, our answer is x ≥ -1/2
Alternatively, we can graph the function and analyze domain:
The product is
Explanation:
The given expression is
We need to determine the product of the given expression.
First, we shall simplify the given expression.
Thus, we have,
Expanding the expression, we have,
Now, we shall apply FOIL, we get,
Simplifying the terms, we have,
Multiplying, we get,
Adding the like terms, we get,
Thus, the product of the given expression is
