I'm lostFound 2 solutions by nyc_function, lwsshak3:Answer by nyc_function(2733)   (Show Source): You can put this solution on YOUR website!Let y = f(x) Now we have y = 3x^2-18x+2 The graph of this function will be an upward parabola. To graph, select 3 negative values for x and then 3 positive values for x. You pick the values desired for x. Anyway, here it is: Let x = -3, -2, and -1. Then solve for y to find 3 points in the form (x,y). Then let x = 1, 2, and 3. Afterward, solve for y to find 3 points in the form (x,y). All you have to do next is connect all 6 points with a smooth curve. Understand? Answer by lwsshak3(6505)   (Show Source): You can put this solution on YOUR website!I need to graph this f(x)=3x^2-18x+2 Since this is a second degree equation, the graph is a parabola. complete the square y=3(x^2-6x+9)+2-27 y=3(x-3)^2-25 This is an equation of a parabola of the standard form: y=A(x-h)^2+k, with (h.k) being the (x,y) coordinates of the vertex. For given parabola: Vertex:(3,-25) axis of symmetry: x=3 Parabola opens upwards (lead coefficient>0) y-intercept set x=0 f(0)=3(3)^2-25=27-25=2 This gives you points at (0,2) and (6,2) because of axis of symmetry. You now have all the information you need to graph the given function
