Which is the graph of f(x) = -(x + 3)(x + 1)?
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 .

<u>Hence</u><u> </u><u>the </u><u>second</u><u> </u><u>option</u><u> </u><u>is </u><u>correct</u><u> </u><u>.</u><u> </u>

The answer to your question is x = 6

Step-by-step explanation:

Process

1.- We can prove that the triangles are congruent.

Two angles measure the same 23°

Two sides measure the same 9

Two angles measure the same the are vertical angles

The third angle measure the same

From this information, we conclude that the triangles are congruent  ASA

2.- If the triangles are congruent then x = 6, the sides are congruent
