The nonlinear function $f(x)=16x^2-e^{\frac{x}{4}}$ has a root in the interval $0,1.$ If we use Fixed$-$Point iteration technique, which one of the following functions can be used as a convergent iteration formula to find approximation to the root? a$.x=g(x)=4ln(16x^2)$ b$.x=g(x)=4e^{16x^2}$ c$.x=g(x)=\frac{e^{\frac{x}{e}}}{4}$ d$.x=g(x)=\frac{e^{\frac{x}{4}}}{16}$ e$.x=g(x)=16x+e^{\frac{x}{4}}$
