How do you write a polynomial in standard form, then classify it by degree and number of terms #z^2-z^4+2z^2 #?

Answer 1

Eva Abramson

#f(z) = -z^4+3z^2#

Degree: 4, Number of terms: 2

Let #f(z) = z^2-z^4+2z^2#

#= -z^4+z^2(1+2)#

#= -z^4+3z^2#

Hence, #f(z)# is of degree 4 with 2 terms.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
