Can someone help me determine which graphs are functions and which are not please I will give brainiest answer!!
Please Help Asap

1 , not a function

2. function

3. not a function

5. function

6. function

7. not a function

8. function

9. not a function

10. not a function

  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).

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
