If f(x) = 2x + 3 and g(x) = x2 + 1,find f(g(3)).
Answer:
The value of f(g(3)) is 23.
Step-by-step explanation:
The given functions are
\(f(x)=2x+3\)
\(g(x)=x^2+1\)
We have to find the value of f(g(3)).
Substitute x=3 in the function g(x) to find the value of g(3).
\(g(3)=3^2+1=9+1=10\)
\(f(g(3))=f(10)\) [g(3)=10]
Substitute x=10 in the function f(x) to find the value of f(10).
\(f(10)=2(10)+3=20+3=23\)
Therefore the value of f(g(3)) is 23.
