## Main Question or Discussion Point

ok, lets say i am plotting a graph of Energy VS voltage

so my units will be Joules VS Volt

so my gradient will be Joules per voltage

but what if i plot ENergy VS square root of VOltage?

will it become Joules VS VOLT

so gradient = Joules per Volt

my lecturer once said you cannot take a function of anything with units. but what if the equation itself has units?

like E=mc

so my units will be Joules VS Volt

so my gradient will be Joules per voltage

but what if i plot ENergy VS square root of VOltage?

will it become Joules VS VOLT

^{1/2}so gradient = Joules per Volt

^{1/2}?my lecturer once said you cannot take a function of anything with units. but what if the equation itself has units?

like E=mc

^{2}. if i plot E against c^{2}, will the units become J VS m^{2}s^{-2}
