If f(x)=2x^2+3x+1 and g(x)=x+5, what would f(g(x))

Fantom [35]

Answer: The answer is $2x^2+23x+66.$

Step-by-step explanation: The given functions are

$f(x)=2x^2+3x+1,\\\\g(x)=x+5.$

We are to find f(g(x)). To do this, first we need to evaluate g(x) and then we will apply the function f on the resulting function.

The evaluation is as follows:

$f(g(x))=f(x+5)=2(x+5)^2+3(x+5)+1=2(x^2+10x+25)+3x+15+1\\\\\Rightarrow f(g(x))=2x^2+23x+66.$

Thus, the correct answer is $2x^2+23x+66.$
