Answer:

Step-by-step explanation:

X = 4

is the answer becuase if you multiply 2 by 4.5 you will get 9 and 9 is the same thing

if you multiply 2 by 5.5 = 11 so thats greater then 9 we want nine to be greater then the number 2x

so 2 x 4 is 8 and 8 < 9 so thats your answer

Bas_tet [7]

Answer:

See attachment

Step-by-step explanation:

A function is given to us and we need to tell which graph represents the given function. The function given to us is,

$\tt: \implies f(x) = -( x + 3 )( x + 1 )$

Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,

$\tt: \implies -(x +3)( x + 1 ) = 0$

Equate each factor by 0 ,

$\tt: \implies \boxed{\blue{ \tt x = -1,-3 }}$

Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .

On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .

Hence the second option is correct .
