Which statement is true about the end behavior of the graphed function?

tatyana61 [14]

The <em><u>correct answer</u></em> is:

A) as the x-values go to positive infinity, the functions values go to negative infinity.

Explanation:

We can see in the graph that the right hand portion continues downward to negative infinity. The right hand side of the graph is "as x approaches positive infinity," since x continues to grow larger and larger. This means as x approaches positive infinity, the value of the function approaches negative infinity.

<u>Part A)</u> $7(a+b)=7a+$

Using the distributive property

$7(a+b)=7a+7b$

therefore

<u>the answer Part A is</u>

$9-----> A$

<u>Part R)</u> $4(5+x)=20+$

Using the distributive property

$4(5+x)=20+4x$

therefore

<u>the answer Part R is</u>

$14-----> R$

Using the distributive property

$3(2x+9)=6x+27$

therefore

<u>the answer Part Y is</u>

$4-----> Y$

Part S) $8(3x+1)=+8$

Using the distributive property

$8(3x+1)=24x+8$

therefore

Using the distributive property

$6(9+5x)=54+30x$

therefore

<u>the answer Part D is</u>

$10-----> D$

<u>Part W)</u> $x(a+3b)=+3bx$

Using the distributive property

$x(a+3b)=ax+3bx$

therefore

<u>the answer Part W is</u>

$18-----> W$
