[最も選択された] y=x-3 function table 152830-Y=3-1/2 x function table
Cubic Functions B = 3; y = x −3 → y = 0 − 3 So at x = 0 we have y = − 3 So the xintercept is at the point P → (x,y) = (0, −3) Similarly the graph crosses the xaxis at y = 0 so by substitution we have y = x −3 → 0 = x − 3 Add 3 to both sides 0 3 = x −3 3 3 = x 0 Y=3-1/2 x function table
