$f(x)=\

$$\begin{cases}-2x + 6&\\text{for }x\ eq4\\\\5&\\text{for }x = 4\\end{cases}$$

$
find $f(6)$

Explanation:

Step1: Identify correct function branch

Since $6
eq 4$, use $f(x) = -2x + 6$.

Step2: Substitute $x=6$ into the formula

$$\begin{align} f(6) &= -2(6) + 6 \end{align}$$

Step3: Calculate the result

$$\begin{align} f(6) &= -12 + 6 = -6 \end{align}$$

Answer:

$-6$
