Question

Graph the parabola.Plot five points on the parabola: the vertex, two points to the left of the vertex, and two pointbutton.1x121018G4Х?12100610122

Answer 1

the given equation is

y = -x^2

so its vertex will be

(0, 0)

this parabola is symmetric to the y-axis

Now the left point on this parabola is

put

X = -1

y = - (-1)^2 = -1

so the point is (-1 , -1)

& X = - 2

y = -(-2)^2

y = -4

so the point is (-2, -4)

now the right side point

put x = 1

y = - (1)^2 = -1

so the point is (1 , -1)

X = 2

y = -(2)^2

y = -4

so the point is (2, -4)
