What are the answers to These 3 questions?
STALIN [3.7K]
1) As a start you have 100% of contaminants: so
 the 1st filtration you removed 70% & remaining 30%
the 2nd filtration you removed 70% of the 30% (=21%) & remaining (30%-21%)
 or 9%
the 3rd filtration removed 70% of the 9% (=6.30%) & remaining (9%-6.3%)
 or 2.7%
the 4th filtration removed 70% of the 2.7% (1.89%) & remaining (2.7%-1.89%)
 or 0.81%
Follow the same logic for all remaining question.

What is the range of the function f(x)=-2|x+1|?
schepotkina [342]

Answer:

The correct answer to given question is option (a).

Step-by-step explanation:

Given function: f(x)= -2|x+1|

we need to put random values of x in given function to see that range of the given function f(x) is all real numbers.

when:

x=0;    f(0)= -2|0+1|= -2|1|= -2

when x is positive i.e. x>0

x=1;     f(1)= -2|1+1|= -2|2|= -4            

x=2;    f(2)= -2|2+2|= -2|4|= -8

when x is negative i.e.  x<0

x= -1;   f(-1)= -2|-1+1|= -2|0| =0

x=-2;   f(-2)= -2|-2+1|= -2|-1|=2 (with the help of mod property |-1|=1)

hence, we saw that

when we take x>0; f(x)<0

when x<0; f(x)>0

we can conclude from above steps that the range of function f(x)= -2|x+1| is all real numbers.
