We have a question And this we have been provided with a limit X approaches to one x 4. one by X -4 by X -1 x four. So we need to find the value of have A. We have F D. A. Cool too affects minus yeah F A. He went by x minus A. So This is one x 4. This could be 10 years. If you compare we can write F-1 by full, equal to FX. That is one by X one by one x 4, Divide by X -1 x four. So He is able to be equal to one x 4 and effects will be equal to one by X. So this should be the answer Thank you.
