let f(x)=12/4x+2 fine f(-1)
\(f(x)= \frac{12}{4x+2 }\)\(For f(-1) =\ \textgreater \ x =\ \textgreater \ -1\)\(f(-1) = \frac{12}{4.(-1) + 2}\)\(f(-1) = \frac{12}{(-4) + 2} = \frac{12}{-2} = -6\)\(f(-1) = -6\)
f(-1)it's easy. instead of x we will put -1 and we will calculate the value SOf(-1)=12/4*(-1)+2f(-1)=12/-4+2f(-1)=12/-2f(-1)=-6
