In a football game , a defensive player jumps up to block a pass by the opposing team's quarterback . The player bats the ball downward with his hand at an initial velocity of - 50 feet per second when the ball is 7 feet above the ground . How long do the defensive player's teammates have to intercept the ball before it hits the ground ?

Which of these choices show a pair of equivalent expressions?

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.
