F(x)= 1/2x^4 - 5x^3 - √7x^2 + 1.4/x + 21 A. -5x^-3 <--- There's no such term as that in this polynomial. B.1/2x^4 <--- That's OK, a number times a whole number power of x C.- √7x^2 <--- That's OK, a number times a whole number power of x D. 21 <--- That's OK, a number times a whole number power of x, the same as 21x0, and 0 is a whole number. E. 1.4/x <--- That's IT! Polynomials can't have a variable in the denominator Answer: E Edwin
