QUESTION 1

a) The zeros of the function are the x-values at which the graph touches the x-axis.

From the graph, the zeros are;

x=0,x=-4

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=-2

c) The maximum value is the y-value of the vertex.

Max: y=4

d) The vertex is the maximum point on the graph.

Vertex: (-2,4).

QUESTION 2

a) The graph touches the x-axis at only one point.

From the graph, the zero is x=-2

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=-2

c) The minimum value is the y-value of the vertex.

Min: y=0

d) The vertex is the minimum point on the graph.

Vertex: (-2,0).

QUESTION 3

a) The graph touches the x-axis at two points.

From the graph, the zeros are x=-3,x=3

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=0

c) The minimum value is the y-value of the vertex.

Min: y=-9

d) The vertex is the minimum point on the graph.

Vertex: (0,-9).

QUESTION 4

a) The zeros of the function are the x-values at which the graph touches the x-axis.

From the graph, the zeros are;

x=-3,x=-5

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=-4

c) The maximum value is the y-value of the vertex.

Max: y=1

d) The vertex is the maximum point on the graph.

Vertex: (-4,1).

QUESTION 5

a) The graph touches the x-axis at two points.

From the graph, the zeros are x=3,x=7

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=5

c) The minimum value is the y-value of the vertex.

Min: y=-4

d) The vertex is the minimum point on the graph.

Vertex: (5,-4).

QUESTION 6

a) The graph does not touch the x-axis.

The function has no real zeros.

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=2

c) The minimum value is the y-value of the vertex.

Min: y=5

d) The vertex is the minimum point on the graph.

Vertex: (2,5).

QUESTION 7

a) The graph touches the x-axis two points.

The function has zeros at x=1 and x=5

b) The axis of symmetry is the vertical line that goes through the vertex of the parabola.

x=3

c) The minimum value is the y-value of the vertex.

Min: y=-4

d) The vertex is the minimum point on the graph.

The test scores for 8 students taking and algebra 1 test are as follows: 56, 92, 78, 64, 85, 83, 91, 77. what would the 9th stud
crimeas [40]
X= 9th student test score

Add the 9 test scores and divide that total by 9 to equal the average.


(56 + 92 + 78 + 64 + 85 + 83 + 91 + 77 + x)/9= 78
add in parentheses

(626 + x)/9= 78
multiply both sides by 9

626 + x= 702
subtract 626 from both sides

x= 76


ANSWER: 76 is the score needed by the 9th student for a mean of 78.

Hope this helps! :)
