    Curved lines rules out linear functions and absolute value functions.

    Some functions with curved lines, such as exponential functions and logarithmic functions, will ONLY increase or decrease. We are left with quadratic functions, and other similar functions such as cubic functions. The functions of trigonometric terms such as sin and cosine will also fit your criteria.
