Sarah used properties of operations to write the following three equivalent expressions to 1l-4+8+(-6)]. Expression 1: 3 (-4)+ +2(-6)

Expression 2: 1[(-4+(-6)]+4

Expression 3: -2+4+3
Which of the expressions is not equivalent and what was Sarah's error?

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.
