Both function plots start at 1, even though I have time step as t=0:6

I am working to plot two basic functions from 0 to 6. When the section is ran, the plots are correct except that it is starting from 1 and not 0.
a_2 = -16;
a_3 = 1/3;
t = 0:6;
v = a_2 + (3*a_3*(t.^2));
a = 6*a_3*t;
plot(v)
hold on
plot(a)
hold off
xlabel('Time (s)')
ylabel('Velocity (m/s), Acceleration (m/s^2)')
xlim([0,t(end)])
ylim([-17,24])

Use
plot(t,v)
plot(t,a)
instead of
plot(v)
plot(a)

Ran in:
a_2 = -16;
a_3 = 1/3;
t = 0:6;
v = a_2 + (3*a_3*(t.^2));
a = 6*a_3*t;
plot(t, v) % <-- plot(xvalues, yvalues)
hold on
plot(t, a)
hold off
xlabel('Time (s)')
ylabel('Velocity (m/s), Acceleration (m/s^2)')
xlim([0,t(end)])
ylim([-17,24])
grid on, grid minor
