THe directions state:
(A)Complete the table, (B) describe the resulting graphs by identifying the vertex point, (C)the graph’s direction, (D) and any axis intercepts gleaned from the table or graph
Problem #3
Equation : y = 2x^2
My answers:
A) Table:
(2, 8)
(1 , 2)
(0,0)
(1,2)
(2,8)
B) Vertex (0,0)
axis of symmetry x = 0
C) The graph direction is Opens upwards since it have a positive x^2 coefficient
D) Axis intercepts is only one (0,0)
Problem #4
Equation : y = x +1
A) Table:
(2,1)
(1 , 0)
(0,0)
(1,2)
(2,3)
B) There is no vertex or a symmetry line
C) Direction of the graph is: increaing on the right and decreasing on the left
D) axis intercepts : (1,0) and (0,1)
all correct.
thank you.
