Do not attempt to &nd the zeros. a. f ( x ) = 2 x 5 & x 4 & x 2 + 1 b. g ( x ) = 6 x 4 + 2 x 3 & x 2 + 20 2. Find the rational zeros of the polynomials. Dont forget to &nd the possible rational zeros. a. f ( x ) = x 4 + 4 x 3 + 2 x 2 & x + 6 b. g ( x ) = x 4 + x 3 & 3 x 2 & x + 2 3. Find a polynomial whose coe cients are real numbers and has the degree and zeros given: a. Degree 4; zeros: i ; 1 + i b. Degree 5; zeros: 1 ; i; 2 i 4. Find all zeros of the function, using the given zeros a. f ( x ) = x 3 & 4 x 2 + 4 x & 16; zero: & 2 i b. g ( x ) = x 4 & 9 x 3 + 21 x 2 + 21 x & 130; zero: 3 & 2 i 5. Find the domain and zeros of the rational functions: a. f ( x ) = x 2 & 1 x +1 b. g ( x ) = x 3 & 8 x 2 +1 6. Graph the following rational functions: a. f ( x ) = 1 x +3 & 2 b. g ( x ) = x & 4 x 7.
