Here is the function graphed. This is what you asked for.
 
        
        
        
D. 
f(x) can be written as (x+2)(x-2)(x-1)
by using difference of two squares to expand x^2 - 4 whch yields 3 x intercepts
similarly, k(x) can be written as
 x(x+5)(x-5) which also yields 3 
x intercepts (0,-5, and 5)
        
             
        
        
        
Log16 4 = 2       
log base 16 then the number four then set that equal to 2        
 
        
        
        
It is (A). When removing decimal of 0.03 you will get = 3/100 so A is the correct answer.
