alleryIdentify the function h(x) = x^(2/3) + 2x. Which of the following is INCORRECT?
Ax^(2/3) is not of the form a_k · x^k where k is a non-negative integer
Bh is a polynomial function
Ch is not a polynomial function
Dh has a fractional exponent (2/3) in the leading term
Answer & Solution
Correct answer: B. h is a polynomial function
A polynomial requires non-negative integer exponents.
x^(2/3) has exponent 2/3 — not a non-negative INTEGER.
So h is NOT a polynomial.
The other three statements correctly explain why.
