I need assistance in answering the following questions.

 

Activity 1 Graphing a Parabola Follow the directions below to complete 8-Activity. Use your results from below to answer the questions. This activity is worth 10 points. Make a t-table of values for y = x2 + 4x + 1. A suggestion is to begin your values with -5. Graph the points on graph paper and draw the parabola. Fold the paper vertically, so that the two sides of the parabola are touching each other. Unfold the paper. Now complete 8-Activity 1.

 

 

Question 1 (4 points)

List your ordered pairs from the table. Use parenthesis for each pair, such as (-1,2).

 

Question 2

Which point is the vertex of the parabola?

a	(-2, -3)
b	(2, 3)
c	(-2, 3)
d	(2, -3)

 

Question 3

The line which you folded is called the line of symmetry. This divides the parabola into two matching halves or mirror images. The equation of the line is x = ___ because it is vertical. Look to see where your folded line crosses the x-axis. Choose the equation below.

a	x = -2
b	x = 2
c	x = 0
d	None of the above

 

Question 4

What do you notice about the vertex and the line of symmetry?
