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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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