Question

Graph if f (x) =2x^-10 for find f(5)

Answer 1

Answer:

$f(5)=2.048*10^{-7}$

Step-by-step explanation:

We have that $f(x)=2x^{-10}$, we want to find $f(5)$.

We can rewrite this function with positive index to get:

$f(x)=\frac{2}{x^{10}}$

We need to substitute $x=5$ into the given function to get:

$f(5)=\frac{2}{5^{10}}$

This implies that:

$f(5)=\frac{2}{9765625}$

In scientific notation:

$f(5)=2.048*10^{-7}$
