What is the range of the function f(x) = -1/3|x - 1| - 2? A. all real numbers
B. all real numbers less than or equal to -2
C. all real numbers less than or equal to 1
D. all real numbers greater than or equal to -2

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

there are infinitely many solutions.

$113.42

i hope that is right.
