Express each of the following quadratic functions in the form of f(x) = a (x - h)²+ k. Then, state the minimum or maximum value, axis of symmetry and minimum or maximum point. (a) f(x) = -2x² + 7x + 4. Pls help me ans this question, its urgent!!
I'll mark u as the brainliest!​

Graph a sine function whose amplitude is 3, period is 4π , midline is y = 2, and y-intercept is (0, 2) . the graph is not a reflection of the parent function over the x-axis. use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
