Answer 1

First one
this graph can be obtained by transformations of the graph of y^2 = 4ax which is a parabola with vertex through the origin and which opens to the right.
So we can say straight away that the answer is either option b or c

Answer 2

The vertex form of this graph can be written as

x - b = (y - a)^2 where (a,b) is the vertex

Check out the graph - we see that the vertex is at (4,3)

so now you can tell which is correct option.

Answer 3

The answer can also be confirmed by plugging in a point on the graph ( 7,9) and see if it fits the chosen equation.

Answer 4

* sorry There's an error in the second line of my second post
The vertex is at (b,a) In the graph b = 4 and a = 3

Answer 5

if you want more help on this, post it in the Math section, this is the English section

Answer 6

D and B

Answer 7

bye i gtg my head is hurting, bye
