if f(x)=2x+1 and g(x)=x^2+7, which of the following is equal to f(g(x))

Answers

Answer: [tex]2x^{2} +15[/tex]

Explanation:

so basically f(g(x)) is telling you to plug the entire g(x) equation into x in the f(x) equation so it will look like this

2([tex]x^{2} +7[/tex]) + 1

and then simplify

[tex]2x^{2} +14 + 1[/tex]

[tex]2x^{2} +15[/tex]

The value of f(g(x)) is 2x² + 15

Function:

f(x) = 2x + 1

g(x) = x² + 7

Therefore, we just have to replace the value of x in f(x) as x² + 7.

f(g(x)) = 2(x² + 7) + 1

f(g(x)) = 2x² + 14 + 1

f(g(x)) = 2x² + 15
