Assignment:
Solve any 6 equations/inequalities by the indicated method. If no method is indicated then you can solve either algebraically or graphically. Solution by graphing requires a sketch of the graph or a written description of the graph and where the solution lies.
1) -x3 + 2x2 + 3x -5 =0, solve graphically.
2) x2 + 8x –2 = 0, solve using the quadratic formula
3) √(2x - 1)= 3
4) (5x - 3)2/3 = 9
5) 3[x - 2(6x - 1)] > 4 - 5x, solve algebraically
6) x2 - 6x + 8 > 0, solve graphically or by the sign chart – explain what the answer means.
7) x / x2 - 4 + 1/x + 2 = 3
Provide complete and step by step solution for the question and show calculations and use formulas.
