{y=x-2 ?

a- {y=-2y²-2
{x=y-2

b- {y=-2y²+2
{x=y+2

c- {y=-2y²+2
{x=y+2

d- {y=-2y²+8y-8
{x=y-2

need points to ask question

step-by-step explanation:

the answer is 1030 it's very simple math.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
