question 1

Graph the parabola. y=x2+10x+21 Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graphafunction button. 2 Find the xintercept(s) and the coordinates of the vertex for the parabolay =x +8x+ 16. If there is more than one xintercept, separate them with commas. x-interce pt(s]: :| vertex: ('1 [D Consider the following quadratic function. f(x) =-2x -8x-11 (a) Write the equation in the form f(x) =a (x -h) + k. Then give the vertex of its graph. Writing in the form specified: f (x) = X 5 Vertex:(b) Graph the function. To do this, plot ve points on the graph of the function: the vertex, two points to the left of the vertex, and two points to the righl of the vertex. Then dick on the graphafuncljon button. A 4: iiiiIiIiIi .45.; Divide. (3x2 + 20x+ 26) + (x+5) Your answer should give the quotient and the remainder. Quotient: Remainder: X 5
