Use the vertex and intercepts to sketch the graph of each equation. If needed, find additional points on the parabola by choosing values of y on each side of the axis of symmetry. $$x=-(y-5)^{2}+4$$

The graph of a quadratic function f is given by f(x) = -x^2 + 6x - 5. (a) Find the coordinates of the vertex and the x- and y-intercepts: vertex (x, y) = (3, 4) x-intercepts: (x, y) = (1, 0) (smaller x-value) (x, y) = (5, 0) (larger x-value) y-intercept: (x, y) = (0, -5) (b) Find the maximum or minimum value of f. The value of f is f(x).
