What is the domain of this function? A. {3, 9, 12} B. {-2, 2, 3, 4} C. {-2, 2, 3, 4, 9, 12} D. {3}
Fynjy0 [20]
B. {-2, 2, 3, 4}
usually in a graph like this, the domain (x) is on the left side, and the range (y) is on the right side.
hope this helps! ❤ from peachimin
Answer:
- x² + 11x - 28
Step-by-step explanation:
y = - (x - 4)(x - 7) ← expand factors using FOIL
= - (x² - 11x + 28) ← distribute parenthesis by - 1
y = - x² + 11x - 28 ← in standard form
Answer:
-3/4
Step-by-step explanation:
Step-by-step explanation:
A
160 >= 20 + 35x
x being the number of hours renting the canoe.
and we have to pay first $20 flat, no matter what. and then the hourly rate begins to "tick".
B
140 >= 35x
x <= 4
and actually, to make practical sense,
0 < x <= 4
as we want to apply this only, if we truly rent a canoe. 0 hours renting (or even negative numbers) does not make any sense.
C
with the given budget of $160 we can rent a canoe for maximum 4 hours.
