# How do you evaluate the function f(x)=x^2+2 at the given values of the variable f(-2)?

Nov 20, 2016

$f \left(- 2\right) = 6$

#### Explanation:

$f \left(x\right) = {x}^{2} + 2$

The value of the function at $x = - 2$ can be represented as $f \left(- 2\right)$

Hence replacing $x$ for $- 2$ in the above:

$f \left(- 2\right) = {\left(- 2\right)}^{2} + 2$

$= 4 + 2 = 6$
