Question 443374: if f(x)= x squared +4 & g(x)= radical 1-x what is the value of f(g(-3)) ?
Answer by Leaf W.(135) (Show Source): You can put this solution on YOUR website!
You start with f[g(-3)].
=
Since it is on the inside, start with the g(-3), which is basically g(x). Therefore, if g(x)=, then g(-3)=
=
f[]
f[]
f[]
f(2)
=
Since f(x)=, then f(2)=
=

8
=
Therefore, f[g(-3)]=8
