I need this question to be solvd using:RUNG KUTTA$->1$st$,2$nd$,3$rd$,$ and$4$th order.

$2.$ EULER

$3.$ POLYGON

$4.$ HE$\frac{dy}{dx}=4e^{0\mathrm{.}8x}-0\mathrm{.}5y,y(0)=2,x=0$

$,x=4$

$h_1=1$

rung$-$katta method $n=12$storder

$($:$y_{11}\}($:$x=2y(2)=y(1)+k_{1}11\}$

$k_1=f^{\text{'}}(x_i,y(x_i))=f^{\text{'}}(1,5)=4e^{0\mathrm{.}8}-0\mathrm{.}55=$

$y(2)=5+6\mathrm{.}0421637=11\mathrm{.}0402163$

$x=3$UN's

I need the solution ASAP please!
