How do I determine if a function is even, odd, or neither​

Mathematics
1 answer:
denis-greek [22]3 years ago
6 0

Answer:

The way to do is dow below

Step-by-step explanation:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Mr. Haley is leaning a ladder against the side of his house to repair the roof.
Ludmilka [50]

Answer:

20 feet

Step-by-step explanation:

Remember the Pythagorean theorem,

x^2 + y^2 = n^2

in this case

x= 16

y = 12

so substitute back into the equation

16^2 + 12^2 = n^2

256 + 144 = n^2

400 = n^2

sqrt ( 400) = n

20 = n

Nadusha1986 [10]

Answer:

The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there

Step-by-step explanation:

he concept of combinatorics ( combination and permutation) is applied her

nPr = n!/(n-r)!

nCr = n!/(n-r)!r!

Hence number of possible different powerball tickets = number of ways of selection

= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26

= 69C5 x 26C1

using the formula above for combination

= 69!/(69-5)!5! x 26!/(26-1)!1!

= 292, 201, 338 ways

Let's solve the inequality.

x - 5 >= -2

Add 5 to both sides:

x >= 3

The solution of the inequality is the number 3 and all numbers greater than 3.

Since the inequality symbol is "greater than or equal to" which includes "equal to", draw a solid dot on 3. Because of the "greater than" part, you need numbers greater than 3, so color to the right of 3.

The correct answer is choice B.
