Quiz: 4.12: step functions i'll give !me #4 how does the graph of g(x)=2⌈x⌉ differ from the graph of f(x)=⌈x⌉? multiplying by 2 compresses the graph of g(x)=2⌈x⌉ vertically by a factor of 2. multiplying by 2 shifts the graph of g(x)=2⌈x⌉ up 2 units. multiplying by 2 shifts the graph of g(x)=2⌈x⌉ down 2 units. multiplying by 2 stretches the graph of g(x)=2⌈x⌉ vertically by a factor of 2. #5 how does the graph of g(x)=⌊x⌋−3 differ from the graph of f(x)=⌊x⌋? the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted down 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted right 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted left 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted up 3 units.
