Answer:
c. 6 cups
Step-by-step explanation:

Answer:
400x^4+260x^3−840x^2+349x−15
Step-by-step explanation:
Answer: 
never touches the y-axis
touches the y-axis at -4
Step-by-step explanation:
Because -4 means that the graph touches the y-axis at negative 4, not having it means that it never touches the y-axis
slope is change in y over change in x
use 2 points from the table so -3,-21 and -6,-39
change in Y: -39 - -21 = -18
change in x = -6 - -3 = -3
slope = -18/-3 = 6
slope = 6
A^2 - b^2 = (a-b)(a+b)
To test it, expand the right hand side.
