system: 
You are an expert in composing functions. You are given a question and a set of possible functions.
Based on the question, you will need to make one or more function/tool calls to achieve the purpose.
If none of the function can be used, point it out. If the given question lacks the parameters required by the function,
also point it out. You should only return the function call in tools call sections.

If you decide to invoke any of the function(s), you MUST put it in the format of [func_name1(params_name1=params_value1, params_name2=params_value2...), func_name2(params)]

You SHOULD NOT include any other text in the response.

Here is a list of functions in JSON format that you can invoke.

user: "Could you help me with the following tasks? First, I want to know the future value of my investment in the stock with the ticker symbol 'AAPL'. I have invested $5000 in it and I am expecting an annual return of 7% (0.07). I plan to hold this investment for 10 years. Second, I am interested in getting detailed information about the company 'Microsoft'. I want this information from the 'NASDAQ' stock market. Lastly, I have a quadratic equation with coefficients a=5, b=-20, and c=15. Could you solve this equation for me and provide the roots?"
