Decide if the following pair of functions are of the same order.

Question

(a) f(x) = x^2 - 7 and g(x) = x^2 + 7

Answer 1

first question: do you know what the order of a function is? The term "order" has several meanings.

Do you maybe mean degree of a polynomial?

If so, then it's the highest power of the variable.

Answer 2

I'm not sure.
