Algebra

Use direct substitution to determine whether 2, 3, -1 and 0 are zeros f (m) = z 62:3 + 82:2 + 6x 9.2. Consider the function f(:c) = -13 + 2:1:2 + 4:1: 8. (a) State the leading term and describe the end behavior of the graph. i (b) Determine the zeros of f (:13) _, v(c) Use the x intercepts to divide the axis into intervals and choose a test pi each interval to determine the Sign of all function values in that interval ((1) Determine the y i11tercept, f (0) 1 u (9) Carefully sketch the graph using the information above and any meg information such as turning points. 7, 7:33gfz 3; Use synthetic division to verify that .r = -:1 IS a zero of 7:?3; 77 , 77 g(.I) = 31 + 111 2:11 + 5:; *#:i aegifietermmea 9971;119:1133} funetien of degree 3 eif;ligne@fi;WW-?
