Answer:
Step-by-step explanation:
A function has a root only if cuts the x axis .
If it cuts once it means it has one real root, if twice then two roots and so on .
Here in the graph of G(x) shown ,it never crosses the x axis so we can say that there is no real root of the given function G(x).
It means the option A which states G(x) has zero roots is correct.

Step-by-step explanation:
Answer:
perpendicular
Step-by-step explanation:
start but putting each line into the standard line format
2x-y=-5
-y=-2x-5
y=2x+5
x+2y=-6
2y=-x-6
y=-(1/2)x-3
if lines are parallel the slopes would be the same. 2 is not equal to -1/2
if lines are perpendicular the slope of one would be the opposite inverse of the other.
negative inverse of 2 = - (1/2)
so the lines are perpendicular
