Which of the following is an even function?
12345 [234]

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.

Reptile [31]

Answer:

Two right angles = 180 degrees

Step-by-step explanation:

A right angle = 90 degrees

The sum of the interior angles of a triangle = 180 degrees

Two right angles (2 * 90) = 180

180 = 180

Therefore, the sum of the interior angles of  any triangle is equal to two right angles.
