What is the sixth degree polynomial approximation for $f(x)=e^5$ at $x=0?$

Botest one

a $P(x)=1x{y}^2{y}^2{y}^2{y}^2{y}^2$

b$)P(x)=1-x{y}^2-y^2{y}^2-y^2{y}^2$

c$.P(x)=1-x\frac{2}{5}-\frac{2}{5}\frac{2}{5}-\frac{2}{5}\frac{2}{6}$

a$)P(a)=Pa\frac{c}{5}\frac{c}{6}\frac{c^2}{12}\frac{c^2}{120}\frac{c^4}{20}$
