Answer:
Step-by-step explanation:
The answer to 392,196=4,508
Answer: D
Step-by-step explanation:
The graph is narrower, so the coefficient of 
has an absolute value more than 1.
Also, because g(x) opens down, the coefficient of is negative.
This leaves D as the answer.
Answer:
A.
Step-by-step explanation:
To check if a graph is a function, use the vertical line test. Use a ruler or straight edge, or simply imagine a vertical line. Move the line across the graph. The line should only intersect the graph at one point at any time.
B isn't a function because the line intersects the graph at two places (when x = 0).
C isn't a function because the line intersects the graph at two places (between x = -1 and x = 1).
D isn't a function because the line intersects the graph at two places (when x < -1 and when x > 1).
Only A is a function.
Oh ok so square root of 2 is irrational since it goes on and on. square root of 18 is an irrational number too
