He should buy two 5 pound bags and one 2 pound bag.
Given the functions
(a) f(x) = x³ + 5x² + x
(b) f(x) = x² + x
(c) f(x) = -x
Function (a)
f(-x) = (-x)³ + 5(-x)² + (-x)
= -x³ + 5x² - x
= -(x³ - 5x² + x)
The function is neither even nor odd.
Function (b)
f(-x) = (-x)² + (-x)
= -(-x² + x)
The function is neither even nor odd.
Function (c)
f(-x) = -(-x)
= x
= -f(x)
Because f(-x) = -f(x) the function is odd.
Answer: f(x) = -x is an odd function.
Answer:
C. $11.20.
Step-by-step explanation: Just times the minutes by the $0.77 cents then plus the $5.81 to the answer getting your final answer.
Subtract the fee from the total:
131- 35.50 = 95.50
Now divide that by the price per mile:
95.50/ 0.40 = 238.75
They drove 238.74 miles
The answer that I got was 7
