Marta simplified this expression. 4 log, + log, 21 – log, 3r In which step did she incorrectly apply a property of logarithms? 4 logs x + log, 2x – log. 3x Step 1 log, 4x + logs 2x - log3x Step 2 log, 8x? – log3x Step 3 = log:) = log: (*) Step 4

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 right 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted up 3 units. 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 left 3 units.
