Please sketck this graph in matlab, please show the code

Determine the voltage, v(0). v(0) = 0.8(0 + 1) = 0.8 V Determine the voltage across the capacitor for 0 lessthanorequalto t lessthanorequalto infinity. v(t) = 1/C integral^t_0 i(t') dt' + v(0) = 1/2.5 integral^t_0 0 dt' + 0.8 = 0.8 V The expression for the voltage across the capacitor is, v (t) = 0.8(t + l) V -1 lessthanorequalto t lessthanorequalto 0 = 0.8 V 0 lessthanorequalto t lessthanorequalto infinity. Draw the voltage waveform
