Question

Please help me I really don't understand

Answer 1

It will look like a half branch of  a parabola opened upward

You can either create a table by choosing values of y  0, 1, 2, 3, 4 and so on

or

A = 0.25 d^2

so the center is (0,0)

and for d = (2)

A = 1

and for A = 0.25

d = 1 

and try to draw it with just 3 points
