Graph the function f by starting with the graph of y equals x squared and using transformations (shifting, compressing, stretching, and/or reflecting). [Hint: If necessary, write f in the form f(x)equalsa left parenthesis x minus h right parenthesis squared plus k.] f left parenthesis x right parenthesis equals left parenthesis x plus 2 right parenthesis squared minus 1 Question content area bottom left Part 1 Which transformations are needed to graph the function f left parenthesis x right parenthesis equals left parenthesis x plus 2 right parenthesis squared minus 1? Choose the correct answer below. A. The graph of y equals x squared should be horizontally shifted to the left by 2 units and shifted vertically down by 1 unit. B. The graph of y equals x squared should be horizontally shifted to the left by 1 unit and shifted vertically up by 2 units. C. The graph of y equals x squared should be horizontally shifted to the right by 2 units and shifted vertically up by 1 unit. D. The graph of y equals x squared should be vertically shifted down by 2 units and shifted horizontally to the left by 1 unit
