Answer (it has two solutions):
I hope this helps!
Answer:
The correct graph is D.
Step-by-step explanation:
Given a quadratic equation :
You can find the roots (where the graph intersects the x-axis) applying the following equation :
and
We define the discriminant as
If then the graph will intersect the x-axis in two points
If then the graph will intersect the x-axis in one point.
Finally, If then the graph won't intersect the x-axis because it will not have real roots.
In this exercise, the graph that doesn't intersect the x-axis is graph D.
Answer:
D
Step-by-step explanation:
A negative discriminant indicates that the quadratic equation has no real roots.
Thus the graph does not touch or intersect the x- axis
The only graph that does not touch or intersect the x- axis is the fourth one
Answer:
Step-by-step explanation:
To find the growth in a table, multiply the divide of the difference by the x of the y.
Not positive but pretty confident about it.
A = bh
A = (3.5)((0.75)
A = 2.625
A = 2_5/8 ft^2
