Find the bounds on the real zeros of the following function. Please show all of your work.f(x)=x^4+2x^3-x^2-1

  • Precalculus -

    Make a rough sketch.
    A few button-pushes on your calculator will show that there is a zero near -2.5 and another between 1/2 and 1
    for x's > 1 and x < -2/5 the function just "blows up"
    looks like 2 reals and 2 complex roots
