Question: In Exercises 1-4, use a graphing utility to graph the quadratic function. Identify the vertex, axis of symmetry, and x-intercept(s). Then check your results algebraically

In Exercises 1-4, use a 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 function in standard form.
1. f (x) = −(x2 + 2x − 3)
2. f (x) = −(x2 + x − 30)
3. g(x) = x2 + 8x + 11
4. f (x) = x2 + 10x + 14
