Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then it's a parallelogram (converse of a property). ... If one pair of opposite sides of a quadrilateral are both parallel and congruent, then it's a parallelogram (neither the reverse of the definition nor the converse of a property).
Step-by-step explanation:
Look at where the peak is. So, the greatest number of hours of sunlight would be around 180.
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.
