Here's what I get
Step-by-step explanation:
The formula for a quadratic equation is
ax² + bx + c = 0
The quadratic formula gives the roots:
D is the discriminant.
It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.
It doesn't matter if the graph opens upwards or downwards.
If D > 0, the graph crosses the x-axis at two points.
If D = 0, the graph touches the x-axis at one point.
If D < 0, the graph never reaches the x-axis.
Your graph must look like one of the two graphs on the right in the Figure below.
Answer:
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. y=6 is a straight line perpendicular to the y-axis at point (0,6) , which means that the range is a set of one value {6} .

Answer:
Option C (4096π in²)
Step-by-step explanation:
Area of the circle = 256π in²
We know that 
, where r = radius of the circle
So,
Cancelling π from both the sides,
The radius of the circle = 16 in.
When the radius is multiplied with 4 , new radius = 16×4 = 64 in.
New Area = 
3/ 1/2 = 6 1 / 1/4 = 4 1/2 / 2 = 1/4
1/3/ 4 = 1/12 2/ 1/6 =12 1/4 /3 = 1/12
