Question

what would be the equation for this graph?

Answer 1

the part to the left is easy it is y=-x

i cant clearly see the second part

Answer 2

what do you think? is that a quadratic?

Answer 3

i dont know..?

Answer 4

bingo yes it is

Answer 5

ok

Answer 6

look at the value of it at x=1 it is 1 at x=2 it is 4

So we have

the graph is
y=-x for x<1

and y=x^2 for x>1

Answer 7

since its quadratic...would it be -x^2?

Answer 8

even y=x^2 is a quadratic

Answer 9

oh ok thanks

Answer 10

why will it be -x^2? if it was - then at x=1 y would have been -1

Answer 11

oh

Answer 12

umm so you get it or is it still unclear?

Answer 13

I got it...thank you so much

Answer 14

np yw :D
