Question summary: Find and match the phase shift of the function. {[y equals 4 space sin space left parenthesis 2 x minus 8 right parenthesis]; [y equals cos space left parenthesis straight pi straight x plus straight pi right parenthesis]; [y equals negative 3 space cos space left parenthesis x plus 7 right parenthesis]} -> {shifted 7 units to the right; There is no phase shift; shifted 4 units to the left; shifted 7 units to the left; shifted 4 units to the right; shifted 1 unit to the left}
Right answer summary: [y equals 4 space sin space left parenthesis 2 x minus 8 right parenthesis] -> shifted 4 units to the right; [y equals cos space left parenthesis straight pi straight x plus straight pi right parenthesis] -> shifted 1 unit to the left; [y equals negative 3 space cos space left parenthesis x plus 7 right parenthesis] -> shifted 7 units to the left
