A power function is a function of the form **y=x^a**, where **a **is a number.

The graph of a power function is a curve.

As the coefficient **a **increases, the flexion of the function becomes less noticeable, as the bend tends to zero, it moves the other way.

y=x^4

y=x^(-2)

y=x^5

y=x^(-7)

y=x^9
