Algebra 2 Solving Quadratics by Graphing

What words could be used that mean the answer to a quadratic function? (Select all that apply!!!) x-intercepts y-intercepts solutions maximum minimum roots vertex zeros Find all solutions to the quadratic equations below. x2 + 15x + 50 = 0 x = -10 x=-5 x2 - 11x + 28 = 0 x = 4 x = 7 x2 - 11x + 24 = 0 x = 3 x = 8 x2 - 7x - 44 = 0 x = -4 x = 11 x2- 36 = 0 x = 6 x = -6 x2 - 18x + 81 = 0 x = 9 Find all roots of the quadratics. x2- 5x - 14 = 0 x = -2 x = 7 x2+ 13x + 12 = 0 x = -12 x = -1 x2 - 12x + 32 = 0 x = 4 x = 8 x2 - 6x - 27 = 0 x = -3 x = 9 15x2 - 2x - 1 = 0 x = -1 x = 1 9x2 + 24x + 16 = 0 x = -4 Match the zeros to their quadratic equation. (Remember that it has to equal 0.) -7 + 19x + 6x2= 0 x = -3.5 x = 1 6x2 - x - 5 = 0 x = -5 x = 1 7x2 + 19x = 6 x = -3 x = 2 4x2 + 15x + 6 = 4x x = -2 x = -3 6x2 - 11x + 15 = 12x - 5 x = 4 x = 2.5 x2 - 4x + 16 = 4x x = 4 How many solutions does this graph have? no solutions one solution two solutions five solutions
