Question

Which system of equations matches the graph below?
y = x^2 if x < 1
y = –x if x (less than or equal to)1

y = –x if x (less than or equal to)1
y = x^2 if x > 1

y = x^2 if x > 1
y = x if x(greater than or equal to) –1

y = x if x (less than or equal to) 1
y = –x^2 if x > 1

Answer 1

if u observe there is closed circle at x=1 for the straight line y=-1
so, it'll be y=-x if \(x \le1\)

Answer 2

i got that part

Answer 3

ok, and for x>1 its clearly the graph of \(x^2\)

Answer 4

so we have to figure out if its x <1 or x>1

Answer 5

its either the top two choices

Answer 6

x^2 is the graph only for x>1
because on the right side of x=1, u have the curved graph of x^2

Answer 7

second onee

Answer 8

yup.

Answer 9

thanks (:

Answer 10

welcome ^_^
