given the folowing quadratic equations find
the vertex
the axis of symmetry
the intercept
the domain
the range
the interval where the function is increasing andthe interval where the function is decreasing graph the function y=X^2+4x

  • college algebra -

    y = (x+2)^2 - 4

    you should be able to read off all the desired information from that. If you still have trouble, come on back and show where you got stuck.
