Let f(x)= 2x^4-5x^3-2x^2-3x+8. A. Find all possible rational roots using the Rational Root Theorem.

B. Find all possible combinations of positive real zeros, negative real zeros, and complex zeros using Decartes’ Rule of Signs.

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
