\(f(x)=|(x^2-50)|\\\\f(-5)=|(-5)^2-50|=|25-50|=|-25|=25\\\\\\|a|= \left\{\begin{array}{ccc}a&for&a\geq0\\-a&for&a < 0\end{array}\right\\\\|-3|=3;\ |5|=5;\ |0|=0;\ |-12|=12\)

Answer:

25

Step-by-step explanation:

f(x) = [ (x^2 - 50 ) } ,

f( - 5) = [ (-5)^2 - 50) ]

f( - 5) = [ 25 - 50]

f( - 5) = [ -25 ]

f(-5) = 25
