Verify that y=f(x)y = f(x)y=f(x) has a stationary point in the interval [1.2,1.3][1.2, 1.3][1.2,1.3]
Starting with x0=1.2x_0 = 1.2x0=1.2, apply the Newton-Raphson procedure twice to find an approximation for the x x\,x coordinate of the stationary point in the interval [1.2,1.3][1.2, 1.3][1.2,1.3].
