Your Answer Is....
A) Acute, C) Equilateral, And D) Isosceles. 
Why?
Acute = All Sides Less Than 90°. Equilateral = All Sides The Same. Isosceles = 2 Or 3 Sides The Same. Therefore, A, C, And D Are Your Answers.

Hi there!

f(x) = 2(1/5)ˣ
Recall the form of an exponential function:
f(x) = a(b)ˣ where:
a = initial value
b = rate of decay/growth 
If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay. 
1/5 < 1, so the function is undergoing exponential decay, not growth.
 
        
             
        
        
        
The 4 functions are:




Let's keep in mind that for large values of x, a quadratic function grows faster than a linear function:

 for large values of x
In this problem, we can see that the only quadratic function is 

, while all the others are linear functions, so the function that grows faster for large values of x is
