What is a ratio of 2 where the denominator equal zero?
If the denominator is 0 then the fraction is undefined.
What does a fraction with a zero in the numerator equal?
0. Whatever the denominator - unless the denominator is also 0 in which case the fraction is undefined.
Why can't the denominators of rational expressions be zero How can we find the domain of a rational function?
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.
What is the name of a ratio where the numerator and denominator are both integers?
And the denominator is 0
What if the denominator is more than twice the numerator is the fraction 0?
Yes, it can be. If the numerator is 0. Then suppose the denominator is 3, which is bigger than 0 (double the numerator). So the value of the fraction is 0/3 = 0.
What is it called when you have to set the denominator equal to 0 so you can find what the soultion can not be?
you are finding values to be excluded from the domain.
What is a ratio of 2 where the denominator equal zero?
If the denominator is 0 then the fraction is undefined.
What is a 0 in denominator equal to?
zero equals zero
What does a fraction with a zero in the numerator equal?
0. Whatever the denominator - unless the denominator is also 0 in which case the fraction is undefined.
What is a ratio of 2 integers where the denominator is not equal to 0?
It is a rational fraction.
What values in the denominator must you be mindful of?
The denominator cannot be 0. If the denominator is a negative number, a fraction, a surd or a complex number (depends on your level), you are expected to rescale the fraction so that the denominator is a positive integer.
How do you find the excluded values of variables?
you put the fraction in simplest form (the numerator and denominator have no common factors besides one) then you find what number your variable should be to make the denominator 0. this is excluded value b/c your denominator can never equal 0 the number you found is your excluded value ex. 4 ------ Your excluded value is 3 because 3(3-3)=0 x(x-3)
Why can't the denominator of the rational number A over B equal 0.?
Because division by 0 is not defined.
What are the values of the variable that must be excluded from the domain x plus 8 over x 4?
Any value of x which causes the denominator to equal zero. It's kind of vague, but if you mean the denominator to be (x raised to the 4th power), then x=0 must be excluded. If you mean (x + 4) then x=-4 will make the denominator equal zero, and if you mean (x-4) then x=4 will make it zero.
In the Quotient rule why can the denominator never equal 0?
Division by zero is specifically forbidden in mathematics.
What is a fraction in which the numerator is equal to the denominator?
If the two are 0 then the fraction is not defined. Otherwise it has the value 1.
What fraction ois equal to 0?
It is any fraction whose numerator is zero and denominator is not zero.
