Evaluate the piecewise defined function at the indicated values.
$f(x) = \begin{cases} 3 & \text{x≤5} \\ 5x-6, & \text{if x>5} \end{cases}$
$f(−6) = -6$
$f(0) = 0 $f(5) = 5
$f(6) = 24 $
$f(8) = 34 $
Are my answers correct?
Thank you

$\begingroup$The three first are wrong :
$f(-6)=f(0)=f(5)=3$ because $-6\leq0\leq5$
The two last one are correct :
$f(6)=5\times6-6=24$ because $6\geq5$
$f(8)=5\times8-6=34$ because $8\geq5$
$\endgroup$ $\begingroup$The last two are correct. You are doing something very wrong for the first three, but I don't know what because you have given no working.
You need to pay close attention to the ranges to which each piece of the function applies.
