Answer:
Two distinct real solutions.
Step-by-step explanation:
Given the equation in the form 
, you need to find the Discriminant with this formula:
For the equation 
you can identify that:
Then, substituting these values into the formula, you get that the Discriminant is:
Since 
, then has two distinct real solutions.
The equivalent expression is A
8 divided by 4 = 2
So two is your answer
The answer o this question would be:
<span>A.The vertical line test may be used to determine whether a function is one-to-one
</span><span>D. The horizontal line test may be used to determine whether a function is one-to-one.
Vertical and horizontal line test can be used to find out whether the function, not one-to-one. The test is done by making a horizontal line (for horizontal line test) or vertical line( for vertical line test). If there are no 2 or more points of the graph that touch the line in both tests, then the function would be one-to-one</span>
