YES

This TRS is terminating using the deltalinear interpretation 
d(delta4) =  + 0 + 0*delta4
f(delta3, X2, X1) =  + 0*X1 + 0*X2 + 0 + 2*X1*delta3 + 1*X2*delta3 + 0*delta3
a(delta2) =  + 2 + 0*delta2
b(delta1) =  + 0 + 7*delta1
g(delta0, X0) =  + 2*X0 + 0 + 4*X0*delta0 + 1*delta0
f_tau_1(delta3) =  + 1(delta3/(0 + 1 * delta3))
f_tau_2(delta3) =  + 1(delta3/(0 + 2 * delta3))
g_tau_1(delta0) =  + 1(delta0/(2 + 4 * delta0))
