Answer:

5x3+5x2−55x−15

Step-by-step explanation:

5(x−3)(x2+4x+1)

=(5(x−3))(x2+4x+1)

=(5(x−3))(x2)+(5(x−3))(4x)+(5(x−3))(1)

=5x3−15x2+20x2−60x+5x−15

=5x3+5x2−55x−15

Answer:

5x³ + 5x² - 55x - 15

Step-by-step explanation:

simplify the expression:

5(x − 3)(x² + 4x + 1)

use the distributive property to multiply 5 by x-3

(5x - 15) (x² + 4x + 1)

Use the distributive property to multiply 5x−15 by x² +4x+1 and combine like terms

5x³ + 5x² - 55x - 15

True [87]

Answer:

Step-by-step explanation:

The domain of this function is $[-4,2]$ , as it is shown in the graph that $x$ is only within this interval. The range of this function is $[-4,4]$ , as the smallest value of $y$ is -4 and the largest value of $y$ is 4, and $y$ takes every possible values between them.
