SOLUTION: Given f(x) = sqrt x and g(x) = x^2 − 25, evaluate each expression. f(g(5))= g(f(5))= g(f(0))= f(g(−6))= f(g(x))= g(f(x))=

Question 1183587: Given
f(x) = sqrt x and g(x) = x^2 − 25, evaluate each expression.
f(g(5))=
g(f(5))=
g(f(0))=
f(g(−6))=
f(g(x))=
g(f(x))=

g(5)=0, and sqrt (0)=0
-
f(5)=sqrt(5) and sqrt(5)^2-25=-20
-
f(0)=0 and g(0)=-25
-
g(-6)=11 and f(11)=sqrt(11)
-
f(g(x))=sqrt(x^2-25)
-
g(f(x))=x-25, put the sqrt(x) into the x part of g(x), so that squaring it becomes x and the -25 is still there.
