What are the intercepts of the function?

snow_tiger [21]

Answer:

x-int: (-1, 0), (-11, 0)

y-int: (0, 11)

Step-by-step explanation:

To find x-int, set equation equal to 0:

x² + 12x + 11

(x + 1)(x + 11)

x = -11, -1

To find y-int, set <em>x</em> = 0

f(0) = 0² + 12(0) = 11

f(0) = 11

State the commutative property of multiplication, and provide an example using two different numbers.

attashe74 [19]

Answer:

The commutative property of multiplication states that the numbers of the operation can change their order, and this action will not alter the outcome.

Example 1:

$8*4=32$

Changing the order of the numbers in the operation:

$4*8=32\\\\Then,\\8*4=4*8$

Example 2:

$10*12=120$

Changing the order of the numbers in the operation:

$12*10=120\\\\Then,\\10*12=12*10$
