Domain Function Fraction
Finding the domain of a ra.
Domain function fraction. F x 2x x 2 4 x 2 4 0. No matter how large or small t becomes f t will never be equal to zero. There would be a 0 on the bottom of the fraction hence the domain of f t is all real numbers except 2 range.
So write the denominator as an equation and set it equal to 0. 1 per month helps. This algebra video tutorial explains how to find the domain of a function that contains radicals fractions and square roots in the denominator using interv.
The function f t 1 t 2 is not defined for t 2 as this value would result in division by zero. When finding the domain of a fractional function you must exclude all the x values that make the denominator equal to zero because you can never divide by zero. Here s how you do it.
