Question

Which is an even monomial function?

a. y=2x^-6
b. y=4x
c. y=10x^2+8x
d. y=-x^10

Answer 1

The best answer would be B because a monomial is a function that nothing is added or subtracted and it is just one term. There can be multiplication. D could also technically be correct, but the best answer is B. 

Answer 2

Answer: The correct option is

(d)
`y=-x^(10).`

Step-by-step explanation: We are given to select the even monomial function fro the given options.

We know that

An even monomial function is one in which there is only one term having even power of the unknown variable.

Out of the given options, the function having only one term with even power of the unknown variable is
`y=-x^(10).`

Thus, (d) is the correct option.
