Question

Given the function f(x) =-x^2-1, find the value of f(1/3) in simplest form

Answer 1

Answer:

$-1\frac{1}{9}\ or -\frac{10}{9}$

Step-by-step explanation:

To solve this, we have to plug in 1/3 for x:

$f(\frac{1}{3})=-(\frac{1}{3})^2-1=-(\frac{1^2}{3^2})-1=-\frac{1}{9}-1=-1\frac{1}{9}\ or -\frac{10}{9}$
