Question

find the domain and range the verticle and horizaontal asymptotes of the graph.... f(x)=x^2-2x-3

Answer 1

@uri

Answer 2

ok first domain:
\[f(x)=x^2-2x-3\]
its a simple quadratic equation so domain is R(all real numbres)

Answer 3

now for range we write\[f(x)=x^2-2x-3=(x^2-2.x.1+1^2)-4=(x-1)^2-4\]
so range:\[f(x) \in \mathbb{R} :f(x) \ge -4\]

Answer 4

and as its a quadratic equation so theres no asymptotes
okay ??
