The quadratic graph crosses the y-axis at -3, so the equation is
The shaded region is on 'outer' part of the graph, hence the inequality is
Answer:
y = (x+3)^2 -1
Step-by-step explanation:
The equation for an upward opening parabola is
y = a(x-h)^2 +k
Where (h,k) is the vertex
The vertex is (-3,-1)
y = a(x--3)^2 +-1
y = a(x+3)^2 -1
Put a point in to find a
(0,8)
8 = a(0+3)^2 -1
8 = a (3)^2 -1
Add 1 to each side
8+1 = a9
9=9a
Divide by 9
1 =a
y = (x+3)^2 -1
We need to see the table in order to answer the question
Answer:
None repeating X on the table is a function, if it repeats than not a function.
Step-by-step explanation:
I am not able to see the table but if X has repeating points then it is not a function. If it repeats the Y point then that is ok.
