Question

Graph the function. To​ begin, substitute the values minus​1, ​0, and 1 for x. Make other substitutions as necessary. Use a graphing calculator to verify your work. f left parenthesis x right parenthesis equals negative 19 x squared Use the graphing tool to graph the function. Graph using the points found for the​ x-values minus​1, ​0, and 1.

Answer 1

f (x) = -19 x2 het FO) = 5 Hence y=-19x2 this is the equation of parabola sf x = 0, y =-19x02 = 0 Hence (x, y) = (0,0) is the vertex of I parabola which is downward of taxis and symmetric with negative yaxis Nowvf x=-1 y=-1981) --19 x1==19 if x=1 ys-19X125-19X12-19
