Lunna [17]
f(x)=x^2-16\\\\g(x)=x+4\\\\\dfrac{f}{g}(x)=\dfrac{x^2-16}{x+4}\\\\The\ domain:\ x+4\neq0\to x\neq-4\\\\\dfrac{f}{g}(x)=\dfrac{(x-4)(x+4)}{x+4}=x-4

Can someone please help me I don’t understand how to do it
Juli2301 [7.4K]

Answer:

Step-by-step explanation:

x^2 + 2x - 3 = (1)^2 + 2(1) - 3 = 0 for x = 1

                       (2)^2 + 2(2) - 3 = 5 for x = 2

                        (3)^2 + 2(3) - 3 = 12 for x = 3

x^3 + 5 = (1)^3 + 5 = 6 for x = 1

               (2)^3 + 5 = 13 for x = 2

               (3)^3 + 5 = 32 for x = 3

x^2 + 5x + 4 = (1 )^2 + 5(1) + 4 = 10 for x = 1

                       (2)^2 + 5(2) + 4 = 18 for x = 2

                        (3)^3 + 5(3) + 4 = 46 for x = 3

What fraction has the greatest value 5/6, 7/12, 7/10
White raven [17]
First you have to make them to a common denominator.
5/6 7/12 7/10
50/60 35/60 42/60
from these the greatest value is 35/60 because 35 parts of 60 is bigger than the rest.
so the answer is 7/12
