Domain of the function f(x)=3x/4x^2-4

yaroslaw [1]

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

4 7/12 + 2 1/12 what is the estimate answer

Pani-rosa [81]

$4 \frac{7}{12} = \frac{12*4+7}{12} = \frac{55}{12} \\ \\ 2 \frac{1}{12} = \frac{2*12+1}{12} = \frac{25}{12} \\ \\ \frac{55}{12} + \frac{25}{12} = \frac{80}{12} \\ \\ \frac{80 :4}{4:4} = \frac{20}{3}$
