Answer:

Step-by-step explanation:

Hi,

2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.

To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.

F(x)=x^2-2x+3 g(x)=x^2-2x-4 Find f(g(-2)

olga55 [171]

Answer:

$f(g(-2))=11$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-2x+3\text{ and } g(x)=x^2-2x-4$

And we want to find:

$f(g(-2))$

We will find g(-2) first. So:

$g(-2)=(-2)^2-2(-2)-4=4+4-4=4$

Thus:

$f(g(-2))=f(4)$

Evaluate:

$f(4)=(4)^2-2(4)+3=16-8+3=11$

Therefore:

$f(g(-2))=11$
