    Function Inequality

    If it already gave me x, and plugging the 2 in the function gives different answers for each function, what am I supposed to do with this?

    Re: Function Inequality

    First, this is a piecewise (-defined) function, not a "function inequality".

    To find the function's value at x = 2, find which interval x is in... it's the middle one...  -1 < x < 5
    For every x in this interval, the function's value is 1.

    Why have you asked about this question?
    Can you see which segment the value is on?

    Re: Function Inequality

    I asked because I didn't know what it was or how to deal with it. Thanks to thechaz, I'll go look up piecewise so I won't be dumbfounded the next time I see one.

    Googled it; and I'm an idiot.
