Given the following Rational Function f (x) = x2 +5x+1 X+1 f(x) has a removable discontinuity, remove it and explain briefly what happens at the point that was just removed. Given the following Polynomial function: f(x) = 2x3 + x2 - 7x - 6 a. Use the Rational zero theorem to find all 6 combinations of - (hint: p = factors of the last number, q= factors of the leading coefficient) b. Use remainder theorem to find one f (2 ) = 0 such that ? = c c. Use synthetic division to find the second factor of the polynomial. Factorize second E polynomial to find the three zeros. (Hint: 2 = c and (x - c) is the divisor used in synthetic Division)
