3.For 1.f(x) = 2functions as before, plot thefirst three iterations of the bisection method starting at pointa=3, b= 3. Plot the functionf() in green, the first valuexin red, secondxin blue and thirdxin green. You will have123one plot for each function. Indicate the points x1 ,x2 and x3 using "scatter" function and take the size so that the points arehighly visible. (as before, take3x3, for trigonometricfunctions assume thatxis in radians)
