Given f(x) = (3x and g(x) = -6
which value is in the domain of fºg?
click on the correct answer

The answer is option C) 8

Step-by-step explanation:

Given that ,

  and

f °g means replace the value of x in f(x) by function g(x). In above case as follows,

for the domain of the above function to be defined,

> 0  ,  which means x > 6.

(at 6 function is not defined, indeterminant)

thus, in the above options only 8 is >6.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
