# What is the value of f(x) = -x^2 + 8x - 6 when f(2)?

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

#### Explanation:

Given equation $f \left(x\right) = - {x}^{2} + 8 x - 6$ and we need to find $f \left(2\right)$

$f \left(2\right)$ means that $x = 2$

So, we need to substitute $x = 2$ into $f \left(x\right) = - {x}^{2} + 8 x - 6$ to get $f \left(2\right)$;

$f \left(x\right) = - {x}^{2} + 8 x - 6$

$f \left(2\right) = - {\left(2\right)}^{2} + 8 \left(2\right) - 6$

$f \left(2\right) = - 4 + 16 - 6$

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