B is the right answer because a is too short and c and d are too long
1) The domain is all the possible x values in the function so it would be [-4,4]
2) There are only 3 zeros shown on the graph and they are (-2, 0) (0, 0) (2, 0) the zeros are the value of x when y = 0.
3)The function is positive/Negative is asking for what x values make the y values positive aka interval notation. The function is positive if x = (0, 2) because 0 and 2 aren't included you use parentheses () instead of brackets []
The function is negative if x [-4, -2), (-2,0), (2,4]
Answer:
zero
Step-by-step explanation:
If the same sum is received for the sale of 20 apples at price p as is received for the sale of 140 apples at price p, then we must have ...
20p = 140p
120p = 0 . . . . . . subtract 20p
p = 0 . . . . . . . . . divide by 120
The price was zero.
Answer:
-30
Step-by-step explanation:
i am not sure just remember getting taught it.
lim x → ∞ x^4 x^8 + 2
Combine exponents:
lim x → ∞ x^(4 +8) + 2
lim x → ∞ x^12 + 2
The limit at infinity of a polynomial, when the leading coefficient is positive is infinity.
