Answer:

the complete question in the attached figure

we have that

f(x)=3x/(4x²-4)

we know that

the denominator can not be zero

(4x²-4)=0

4x²=4

x²=1----> x=(+/-)√1

x1=1

x2=-1

the values of x=1 and x= -1 make the denominator zero, therefore they do not belong to the domain of the function

the answer is

the domain of the function is all real numbers except 1 and -1

Let x be the number of rolls of wallpaper that you can buy to decorate your kitchen. Since each roll costs $10, the total cost for x rolls is 10x. This value should be not be more than $50. The inequality that is best described is
10x ≤ 50
Solving for x gives an answer of x ≤ 5.

For this case we have that the point-slope equation of a line is given by:

$y-y_ {0} = m (x-x_ {0})$
