Question 1 of 10
1. Question
A given function f (x) = (x + 3)(x + 1), which is a parabola in xy plane. Which of the following intervals contains the xcoordinate of the vertex of the graph of f ?
Correct
The axis of symmetry of the parabola passes through the vertex of the parabola. Therefore, the vertex of the parabola and the midpoint of the segment between the two xintercepts of the graph have the same xcoordinate.

Question 2 of 10
2. Question
Correct
The numerator can be written as follows:
=> x^2 − 2x − 5 = x^2 − 3x + x − 3 − 2.
x^2 − 3x + x − 3 − 2, this portion can also be written as x(x – 3) + (x – 3) – 2.so now if we divide it by x3, the result becomes,
x +1 (2/x3)Incorrect

Question 3 of 10
3. Question
If y = 4(x – 1)(5x – 1) then which of the following is equal to y?
Correct
y = 4(x – 1)(5x – 1)
=> (4x4)(5x1)
=> 20x^2 – 4x 20x +4
=> 20x^2 – 24x +4Incorrect
y = 4(x – 1)(5x – 1)
=> (4x4)(5x1)
=> 20x^2 – 4x 20x +4
=> 20x^2 – 24x +4 
Question 4 of 10
4. Question
In the xyplane, the parabola intersects the line y = 36 at two points. Determine the distance between those two points of intersection.
Correct
36 = (x+4)^2
=> x +4 = 6 or 6
=> x= 2 or 10That gives us two points (2, 36) and (10, 36). If we calculate the value of x point we will get the value.
x1x2= 2(10) = 12Incorrect
36 = (x+4)^2
=> x +4 = 6 or 6
=> x= 2 or 10That gives us two points (2, 36) and (10, 36). If we calculate the value of x point we will get the value.
x1x2= 2(10) = 12
