Answer 1

This is the graph of the expression
Can you answer your question from the graph?

Answer 2

Doubt is not allowed in math. Be certain.

Answer 3

I think its c.

Answer 4

Nope it is not C.
Did you think Y , the graph, has maximum value?

Answer 5

well it has to be a then...

Answer 6

OK it is " a"
But did you get why?

Answer 7

no.. can u plz explain

Answer 8

If you have any quadratic function of the form\[f(x)=a(x-h)^{2}-k\]You need to consider this points
** If ' a ' is positive number
** the graph will have minimum value w/c is -k
**the range of the graph will be >= -k
** if 'a' is negative number
** the graph will have maximum value w/c is -k
** the range of the graph wii be <= -k
In both cases the domain of the graph is real number since the graph covers all of the x axis.

Answer 9

Thanks I think i get it :)
