f(x) = e^x
This function is so cool it doesn’t even get tired when you integrate it or differentiate it. It’s like it’s got a never-ending supply of energy and a PhD.
My brother said e^x is the only function that doesn’t even need a coffee to stay awake.
I asked my teacher why e^x is so cool and she said, 'Because it’s got a PhD and a PhD is just a degree for being cool.'
My dog barks at e^x because it’s too cool for him.
