Answer:
f(x) is neither even nor odd.
Step-by-step explanation:
For a function to be even f(x) = f(-x) and her results show that this is not the case.
For an odd function -f(x) = f(-x) so we test this:
-f(x) = -x^2 - 2x - 5 ; f(-x) = x^2 - 2x + 5 - so it is not odd.
Answer:
455 or 680, depending
Step-by-step explanation:
If we assume the three choices are different, then there are ...
15C3 = 15·14·13/(3·2·1) = 35·13 = 455
ways to make the pizza.
___
If two or three of the topping choices can be the same, then there are an additional ...
2(15C2) +15C1 = 2·105 +15 = 225
ways to make the pizza, for a total of ...
455 + 225 = 680
different types of pizza.
__
There is a factor of 2 attached to the number of choices of 2 toppings, because you can have double anchovies and tomato, or double tomato and anchovies, for example, when your choice of two toppings is anchovies and tomato.
