y=[x]+2
y=x+2 (red line)
y=-x+2 (green line)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x+%2B2%2C+-x+%2B2%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x +2 and -x +2).
f(x)=3[x].
f(x)=3x (red line)
f(x)=-3x (green line)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+3x%2C+y+=+-3x%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 3x and y = -3x).
