Which graph represents an exponential function? 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.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
