Determine whether each function is continuous at x=5. Justify your answer using the continuity test.
irakobra [83]

Answer:

2. f(x)=\frac{x^2}{x+5}

Step-by-step explanation:

When you replace x=5 into those functions you obtain:

1. f(x)=\sqrt{x^2-36} = \sqrt{5^2-36} = \sqrt{-11} \\2. f(x)=\frac{x^2}{x+5}=\frac{5^2}{5+5}=\frac{25}{10}

We can see that the function number 1, when the x=5 is replaced, falls into the imaginary numbers or complex domain, so the function is not continuous in the real domain.

On the other hand, the second function falls into the real domain whe x=5 is replaced, so the function is continuous in the real domain!

I hope you understand!

The sales at a particular bookstore grew from $2006 million in 2000 to $3803 million in 2005. Find an exponential function to mo
Mariana [72]
Yes initial amount is 2044 (in millions) 

Since the function is from 2000 then you can set it up as 
B(t)=2044*a^t 

To solve for "a" use the second number given, 3846, and since this value is 5 years after 2000 t=5 
so we plug in these values 
3846=2044*a^5 

we now solve for a 

first, divide by 2044 
3846/2044=a^5 

next, we take the 5th root 
<span>5sqrt(3846/2044) = a 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
