Q3) Determine the minimum or maximum of the following function by taking its derivative and putting it equal to zero. To find the root of the derivative, use the interval-halving method and stop when your solution is confined within an interval of length 0.1. Use the second derivative to check whether the answer is a min or a max. y=f(x)= 0.05 x4 -2 x2 +20 sin(0.1 x +0.2) begin with [-7, -3]. (10 marks)
