How do I draw a function with many values for parameters?

For example, suppose you want to represent the four curves of functions \( f_n(x) = x^2 + x.a_n + b_n \) respectively defined with the parameters \( a_{1-4} = \{ -2 , -1 , 1 , 2 , \} \) and \( b_{1-4} = \{ 0 , 1 , 2 , 3 \} \).

Simply enter value for the array \( a \) and \( b \) into the global lists L1 and L2:
Press [ shift ] [ List ] button, touch ( Edit ) in bottom menu and enter values in L1 and L2 (see capture)
Press [ App ] button, touche ( Function ) icon to launch Function Application.
In the first slot enter the definition of F1(X) = X ² + L1(1)*X + L2(1). Presse ENTER
Touch Slot1 definition area and press [ shift ] [ Copy ] in order to copy-paste the definition in the following slots.
Edit the corresponding slots so that: F2(X) = X ² + L1(2)*X + L2(2), F3(X) = X ² + L1(3)*X + L2(3) and F4(X) = X ² + L1(4)*X + L2(4).
Press [ Plot ] button to draw the curves.

Changing values in L1 and L2 dynamically change plots.
