Which of the following is an even function?

Mathematics

12345 [234]2 years ago
6 0

Answer:

  • B. g(x) = 2x² + 1

Step-by-step explanation:

<u>Even function has following property:</u>

  • g(x) = g(-x)

<u>It is easy to show this works with the second choice only. All the others don't work:</u>

  • g(x) = (x - 1)² + 1
  • g(-x) = (-x - 1)² + 1

This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)

The last two choices are not even similarly.

Anthony has 15 coins, all of which are quarters and dimes. In all, they're worth $3.60. How many of each kind of coin does Antho
Usimov [2.4K]

Answer:

1 Dime

14 Quarters

Step-by-step explanation:

d + q = 15

0.10d + 0.25q = 3.60

d = 15 - q

0.10d + 0.25q = 3.60

0.10(15 - q) + 0.25q = 3.60

1.5 - 0.10q + 0.25q = 3.60

0.15q = 3.60 - 1.5

0.15q = 2.1

0.15q/0.15 = 2.1/0.15

q = 14

d = 15 - q

d = 15 - 14

d = 1
