The height y (in feet) of a ball thrown by a child is y = 1 x+2x+3 12 where x is the horizontal distance in feet from the point at which the ball is thrown. (a) How high is the ball when it leaves the child's hand? feet (b) What is the maximum height of the ball? feet (c) How far from the child does the ball strike the ground? Round your answers to the nearest 0.01. feet You are working with a quadratic equation and construct the following graph. -8-7-6-5-4-3-2-1 3 2 + -2 -3 2 3 6 7 Identify the vertex of the parabola: Remember that the vertex is a point! Identify the y-intercept of the parabola: Remember that the y-intercept is a point! Identify the x-intercepts: and Remember that the x-intercepts represent points on the graph! Given the x-intercepts above, write an equation for the parabola in factored form: y = Hint: Think about the zero-product property. Write an equation for the axis of summetry:
