Question

Which parabola has the graph shown? pic attached

Answer 1

A

Answer 2

you shift -4 points on the x and -1 on the y axis

Answer 3

Since for each y, x has two values, the term dependent on y must be squared.
That rules out option B.
We also see that the parabola is dislocated down one unit, and that is equivalent to summing one on y, because then a lower y would actually give the value that it would give one unit ahead.
That rules out option D
The same happens for x, but it is dislocated 4 units to the left, so we must sum 4 to x.
That leaves us with only one option: A
