the function has a real zero in the given interval. approximate this solution correct to two decimal places: f(x)=x^4-x^3-7x^2+5x+10; (2,3)

  • pre-calculus -

    y =x^4-x^3-7x^2+5x+10
    y' = 4x^3 -3x^2 -14x +5
    start with x1 = 2.5
    calculate y there call it y1
    calculate y' there, call it m
    next guess at x2 = x1 - y/m

    thank you for your time and work. i really appreciate it. god bless you.
