 Question 115063: A. Graph the function f(x) = –3x + 7. Be sure to properly label the graph, which includes labeling the axes and the line with its equation. B. Graph the function f(x) = –3x2 + x – 5. Be sure to properly label the graph, which includes labeling the axes and the graph with its equation. Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!A. Graph the function f(x) = –3x + 7. Be sure to properly label the graph, which includes labeling the axes and the line with its equation. If x=0 y=7 If x=1 y=4 ---------- Plot the points (0,7) and (1,4) and draw a line thru them. ---------------------------------------------- B. Graph the function f(x) = –3x^2 + x – 5. Be sure to properly label the graph, which includes labeling the axes and the graph with its equation. Find the vertex at x = -b/2a = -1/-6 = 1/6 Then f(1/6) = -3(1/6)^2+(1/6)-5 = -1/12 +2/12 -60/12 = -59/12 = -4.92 ---------- Plot the point (1/6,-4.92) draw a parabola opening downward with a y-intercept of -5. ===================== Cheers, Stan H.
