Select all the correct answers.
select all relations that represent functions.

option A

option C

option D

Step-by-step explanation:

A function is a special relationship where each input has a unique output.

There could not be different y values for same value of x but it may have two x-values assigned to the same y-value.

In option B

for x = 6

have two different outputs y = -6 and y = -1 REJECTED

In option E

for x = 0

have two different outputs y = 0.5 and y = 2 REJECTED

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
