what are the first four terms of the sequence represented by the expression n(n - 1)- 5?
-7, -5, -3, 1
-5, -10, -15, -20
0, 2, 6, 12
-5, -3, 1, 7

Answer 1

given the function rule f(x)=x^2-4x+3 what is the output of f(-3)
7
-5
25
5

Answer 2

\[n(n - 1)- 5\] put \(n=1\) get \(1\times (1-1)-5=-5\) for the first term

Answer 3

for the second, put \(n=2\) get
\[2\times (2-1)-5\]

Answer 4

\[ f(x)=x^2-4x+3\]
\[ f(-3)=(-3)^2-4\times (-3)+3\]
