Using Technology In Exercises 27-34, use graphing utility to graph the quadratic function. Identify the vertex, axis of symmetry, and x-intercept(s). Then check your results algebraically by writing the quadratic a function in standard form. 27. f(x) = - (x² + 2x – 3) 28. f(x) = - (x² + x – 30) – (x² + x – 30) 29. g(x) = x² + 8x + 11 31. f(x) 32. f(x) 33. g(x) — —(х? + 4x — 2) 34. f(x) = (x² + 6x – 5) 30. f(x) x² + 10x + 14 – 2x² + 12x 18 - | – 4x² + 24x 41 - |
