Question

The domain of rational function g is the same as the domain of rational function f. Both f and g have a single x-intercept at x = -10. Which equation could represent function g?

Answer 1

just think of this, The domain of a rational function consists of all the real numbers x except those for which the denominator is 0 . To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x .
