Help graphing the function plotting their points, as I'm working on 5 and 6 which are confusing as well.

4. (10 points) Graph the function using its vertex, axis of symmetry, and intercepts. (These points need to be on the graph) and find the following: f ( x ) = - x2 - 2x + 3 10 8 Vertex: 6 Axis of Symmetry: 4- 2 X-and Y Intercepts (Write as ordered pairs): 10 8 -6 -4 -2 2 4 6 8 10 Max/Min Value (Identify if max/min and provide the value): Interval of Increasing: Interval of Decreasing: 10 5. (6 points) A ball is thrown vertically upward with an initial velocity of 48 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s = 48t-16t2. a. At what time t will the ball strike the ground? b. For that time t is the ball more than 32 feet above the ground? Write answer as an inequality or interval notation
