Perform the following steps to expand the cubic polynomial
(xN1)(xNi)(x+i), find the
absolute value of the function, graph the modulus surface, and use the
Trace tool to
explore the modulus surface.
1. On the Home screen, use the
expand( )
function to expand the cubic expression
(xN1)(xNi)(x+i) and see the first
polynomial.
2. Copy and paste the last answer to the
entry line and store it in the function
f(x).
Note: Move the cursor into the history
area to highlight the last answer and
press ¸, to copy it to the entry line.
