This is Josh’s solution for the equation : x^2 - 6x - 7 = 0 Is Josh’s solution correct?
x^2 - 6x - 7 = 0
x^2 - 6x = 7
x^2 - 6x + 9 = 7 + 9
(x + 3)^2 = 16
x - 3 = 16
x = 19
x - 3 = -16
x = -13
Explain.

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.
