Answer:
<u>D) (f o g)(x) = 10x² - 60x + 93</u>
Step-by-step explanation:
f(x) = 10x² + 3
g(x) = x - 3
⇒ (f o g)(x) 
⇒ f(x - 3)
⇒ f(x - 3) = 10(x - 3)² + 3
⇒ f(x - 3) = 10(x² - 6x + 9) + 3
⇒ f(x - 3) = 10x² - 60x + 90 + 3
⇒ <u>(f o g)(x) = 10x² - 60x + 93</u>
 
        
                    
             
        
        
        
I'm pretty sure that it's k = -1
        
             
        
        
        
A) The correct way to write 1/4 as a precent is 25%. 
because....
1÷4= .25. and .25×100= 25%
b) The reporter most likely forgot to multiply by 100. The reporter instead just found what 1/4 was as a decimal, not a precent.
