Find domain of1/(x-4)(x-1) |
| Answer» Ans.\xa0{tex}f(x) = {1\\over (x-4)(x-1)}{/tex}\xa0We need\xa0to find where the\xa0expression\xa0is undefined. These values are not part of the\xa0domain.For the above function, if it is defined then{tex}(x-4)(x-1) \\ne 0 {/tex}=>\xa0{tex}x-4\\ne 0 \\space and\\space x-1\\ne 0 {/tex}{tex}x\\ne 4 \\space and\\space x\\ne 1 {/tex}So Domain of f(x) = R - {1,4} | |
