Assume that you have done a preliminary investigation (for instance, you used softwareto graph), and determined that the equationf (x) = 0.25√x − (sin(x/3))2 + 0.12 = 0has 2 distinct roots in the interval [0, 10]. (Note that there is no way to solve this equationexactly using pencil and paper.)(a)[1] Write a function to calculate the values of f (x), and use it to determine the intervalswhere the two roots lie. (This means you need to identify two intervals, so that eachinterval contains one root. Of course, there are many correct choices.)(b)[2] Use the bisection method (look at the template for the values of the parameters) tolocate the two solutions, with the tolerance as given in the template. Start the bisectionwith the intervals that you identified in (a). Output: for each solution, print the intervalwhich contains it.
