If f(x)=2x+3 and g(x)=x^2+1 find f(g(3))<br><br> Help!!<br> A.23<br> B.47<br> C.82<br> D.90
True [87]

Answer

A. 23

step-by-step explanation

g(x) =  {x}^{2} + 1

We put x=3 into the function g

\implies g(3)= {3}^{2} + 1

\implies \: g(3)=10

Also,

f(x)=2x +3

we substitute the value of g(3) into f

\implies f(g(3))=f(10)

\implies f(g(3))=f(10) = 2(10) + 3

\implies f(g(3))=23
