It basically means x is any normal number positive or negative. Don't worry about it it only becomes relevant later into maths when u get 'imaginary' numbers. Just see it as normal numbers

Thank you oh and you know for the graph how many should I plot? BEcause atm I've plotted -3 to 3 and said it will never meet the X axis

Because they ask for a sketch you don't have to make it detailed about the exact values, they just want the rough shape as it increases exponentially and they want you to calculate where it would cross the y axis
