Which graph represents an exponential function?PLEASE ANSWER FAST IM TIMED

Exponential graphs are increasing or decreasing graphs: as the value of x increases, the value of f(x) also increases Or as the value of x decreases , the value of f(x) also decreases.1) The first graph is a Parabola .It represent a quadratic function.2)The second graph is also an inverted parabola and represents a quadratic function.3) The third graph is representing a Hyperbola.4) The graph is representing a radical function.5) The graph is representing an exponential function.The last graph represent an exponential function.
