Question

Dada a função f(x)=x+5, calcule f^-1 (-2):
Resolução

Answer 1

f^-1 (-2): x+5
f(-1/2)= x+5
f(-1/2)=-1/2 +5
f(-1/2) =-1+10/2
f(-1/2) = 9/2

f^-1 (-2): x+5
f($\frac{-1}{2}$)= x+5
f($\frac{-1}{2}$)=$\frac{-1}{2}$ +5
f($\frac{-1}{2}$) =$\frac{-1+10}{2}$
f($\frac{-1}{2}$)= $\frac{9}{2}$

espero ter ajudado

              

Answer 2

f^-1 (-2): x+5
f(-1/2)= x+5
f(-1/2)=-1/2 +5
f(-1/2) =-1+10/2
f(-1/2) = 9/2

f^-1 (-2): x+5
f()= x+5
f()= +5
f() =
f()=
