Question

Which does NOT pass through the origin?
y=-2x^2
2x=square root of y
2y=negative absolute value of x
y=-2x^2 + 2

Answer 1

test the options one by one

Answer 2

put x = 0,
and see wat u get for y

Answer 3

take first option :-
y = -2x^2

put x = 0
y = -2(0)^2
= 0

so, this passes through origin !

Answer 4

similarly test other options and see ?

Answer 5

the last one would give me y=2, so that is not an origin. Am I correct?

Answer 6

perfect !

Answer 7

good job !!
