Designing a regression analysis in R Studio

In R Studio we want to make a regression. By using the dollar and euro exchange rates with Turkish Lira, we want to predict the Turkish stock market equity rate. We have all the data needed for the project. The freelancer should find 3 regression algorithms to implement the regression in R Studio. Later, we will give 3 algorithms to him/her and he/she will use these algorithms to do regression again and compare his/her results with the algorithm results that we have given.
