**Question:**1. What is an x-intercept of the graph of a quadratic function? How many possible x-intercepts does the graph of a quadratic function have? Explain.---**Explanation:**An **x-intercept** is a point where the graph of a function crosses the x-axis. For a quadratic function, which is typically in the form $ ax^2 + bx + c = 0 $, the x-intercepts are the values of $ x $ that make the equation equal to zero.A quadratic function can have:- **Two x-intercepts**: This occurs when the quadratic equation has two distinct real roots. The graph of the quadratic function will intersect the x-axis at two points. - **One x-intercept**: This happens when the quadratic equation has exactly one real root (i.e., a "double root"). The graph will touch the x-axis at just one point, indicating the vertex of the parabola is on the x-axis. - **No x-intercepts**: This is the case when there are no real roots, meaning the solutions are complex numbers. Here, the graph does not cross or touch the x-axis at any point.These scenarios are determined by the discriminant $ b^2 - 4ac $ from the quadratic formula $\frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{2a}$:- If $ b^2 - 4ac > 0 $, there are two distinct real roots.- If $ b^2 - 4ac = 0 $, there is one real root.- If $ b^2 - 4ac < 0 $, there are no real roots.

A. Projectile Motion A child throws a ball upward from the roof of a house. The trajectory is parabolic, according to the laws of physics. The height of the ball above the ground, h(x) (in meters) is given by the quadratic function: h(x) = -3x2 + 6x + 4 where x is the horizontal distance from the house in meters. The goal of this tutorial is to graph this function and analyze and interpret the graph within the problem context. Show the following steps on the blackboard or paper as your instructor directs: a) State the coordinates of the h-intercept. Explain the meaning of this intercept within the problem context. b) Complete the square on the right-hand side to convert the function from general form to standard form. State the coordinates of the vertex. c) Find vertex by using the vertex formula. The result should be the same as in part b) above.
