The functions known as **power functions, **are represented by the function, *f(x) = kx*^{p}, where *k *is any real number and *p *is any real number exponent. The shape of the graph, *y* = *kx*^{p}, depends on the sign of *k *and the value of *p*. The coefficient k will affect the scale of the graph and, if negative, will reflect the graph across the *x*-axis.
