The graph of g(x) is a translation of the function f(x)=x^2. The vertex of g(x)

passes through origin, i.e. $(0,0)$

if you move 5 units up, it should pass through $(0,5)$

so you'll add 5 to $y$ i.e. $y+5=x^2$ this satisfies $(0,5)$

and to move right, it should pass through $(7,0)$ so you'll subtract $7$ from $x$ i.e. $y=(x-7)^2$

now combine both translations

$g(x)=(x-7)^2-5=x^2-14x+45$

12.

Step-by-step explanation:

Number of problems in a section = 864/8

= 108.

So number of problems per page = 108 /9

= 12.
