identify the monomial function described as odd or even, and indicate whether a is positive or negative.

1. as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) decreases.

2. as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) decreases.

3. as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) increases.

4. as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) increases.

*these are the options below

a. odd, a is positive

b. odd, a is negative

c. even, a is positive

d. even, a is negative
