True or false?
an even function is one in which f(x) = f(-x) for all x's and odd function is one where g(x) = -g(-x) for all x's.

True

Step-by-step explanation:

f is odd if the graph of f is symmetric with respect to the origin.

f is even if and only if f(-x) = f(x) for all x in the domain of f.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
