The following quadratic function is in general form: /x]=x2 - 6x + 13 Use the vertex formula to find the coordinates of the vertex. Express your answer with brackets but without any spaces. Coordinates of the vertex: This quadratic function does not have real roots, but rather a pair of complex roots. The roots of f(x) take the form a + " where i is the imaginary unit. Use the quadratic formula to solve for the roots and input the values of a and b below. Both a and b are integers (no decimals). Question 5 (2 points) A child throws a ball from the roof of a house. The following function olx)= -xi+ 4x+5 models the height (in metres) of a ball above the ground in terms of x, the horizontal distance from the base of the house (in metres], Answer the questions below. Note Your answer should be submitted with no spaces between any characters. Use the expression "inf" to mean infinity. For example, if you were wanting to represent the set of all real numbers larger than zero you would submit your answer as: (0,+inf). You must indicate . inf versus +inf to be graded correctly for this question. Vertex of glx): y-intercept of g(x). Range of Box): Total horizontal distance travelled by the ball in metres
