Find the domain of the function (f/g)(x) given f (x)=x^2-4x-5 and g(x)=x^2-25
stealth61 [152]

Answer:

all real numbers except ±5.

Step-by-step explanation:

Each function (f(x), g(x)) has a domain that is all real numbers. Their quotient (f(x)/g(x)) must exclude values that make g(x) = 0. The quotient is undefined when the denominator is zero. Those excluded values are x = ±5.

The domain of (f/g)(x) is all real numbers except ±5.

___

Of course you recognize x^2 -25 = 0 has solutions x = ±√25 = ±5. You can get there two ways:

  1. add 25 and take the square root: x^2=25; x=±√25.
  2. factor the difference of squares and set the factors to zero: (x-5)(x+5)=0 has solutions x-5=0 and x+5=0, that is, x = ±5.

In a group of 20 students, half have blue eyes, 10% have brown eyes, and the rest have hazel eyes. How many students have hazel
Ber [7]
So you have 20 people and 10 percent have brown eyes. So if 100% is 20, to find 10 percent you divide it by 10 to get 10% is 2. You know all the rest have hazel eyes so you just do 20-2 to get 18. Therefore 18 people have hazel eyes. Hope this helps :)
