Question

If f(x)=x³-2x², which expression is equivalent to f(n)?

A) n³-2n²+1
B) n³-2n²-1
C) n³-2n²+2
D) n³-2n²-2

Answer 1

The expression equivalent to f(n) is n³ - 2n².

Step-by-step explanation:

To find the expression that is equivalent to f(n) for the given function f(x) = x³ - 2x², we substitute n in place of x in the function. Thus, f(n) = n³ - 2n².

So, the correct expression is n³ - 2n² which corresponds to option A.
