Although the integral `\int(2x+e)dx` looks like it may be complicated, the integrand is really just a polynomial, which means we can separate it into two different integrals, each of which is just a power rule.

`\int 2xdx+\int edx`

`=2 1/2 x^2+ex+C`   notice that e is just a number, so this is the integral of a constant

Antiderivative means the integration.

f(x) = 2x+e

`intf(x)dx = int(2x+e)dx`


             = `x^2+ex+C`


Therefore antiderivative f(x) = `x^2+ex+C ` where C is a constant.
