we have y=f(x) function, if we transfer its graph C unit vertically and gain the new function y=f(x)±C, it′s meant y is increased or decreased C units. if we transfer the graph of considered function horizontally, we gain the new function y=f(x±C), what does mean it?

$${we}\:{have}\:{y}={f}\left({x}\right)\:{function},\:{if}\:{we}\:{transfer} \\ $$$${its}\:{graph}\:{C}\:{unit}\:{vertically}\:{and}\:{gain} \\ $$$${the}\:{new}\:{function}\:{y}={f}\left({x}\right)\pm{C},\:{it}'{s}\:{meant} \\ $$$${y}\:{is}\:{increased}\:{or}\:{decreased}\:\:{C}\:{units}. \\ $$$${if}\:{we}\:{transfer}\:{the}\:{graph}\:{of}\:{considered} \\ $$$${function}\:{horizontally},\:{we}\:{gain}\:{the}\:{new}\:{function} \\ $$$${y}={f}\left({x}\pm{C}\right),\:{what}\:{does}\:{mean}\:{it}? \\ $$
