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.
