Question

Plot graphs for the equations y = x, y = 4x and y= x /

4
​

Answer 1

Step-by-step explanation:

ANSWER

a=1,b=−4. As a is positive, the parabola should open up.

As c=0, the parabola passes through the origin.

Vertex: x=−b/2a=2, so y=−4

⇒Vertex=(2,−4). Assuming two values of x,

x 1 0

y −3 0

Points obtained: (2,−4),(1,−3),(0,0).

Symmetry of parabola: Mirror image.

Points of (1,−3) and (0,0) are (3,−3) and (4,0), respectively.
