The discriminant can be determined from the number of roots of the graph.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
Since, the given function has two distinct roots i.e. it cross x-axes at two different points, its discriminant will be positive.
So, the answer to this question is option C<span />
Answer: The coordinates of point be are (1,-1)
Step-by-step explanation:
The reflected point will be equidistant from the point over which it is reflected as the original point and in the same line as the original point and the reflected point.
Find the difference between the x and y values of the given points and add that value (distance) to the reflection point.
x-values: 4-7 = -3 y-values: 0-1 = -1
Add to reflection point x: 4-3 = 1 y: 0 -1 = -1
