Answer: Second option.

Step-by-step explanation:

By definition, a relation is a function if for each input value (value of x) there is an unique output value (value of y).

1) For f(0)=3 the input value is x=0 and the output value is y=3, obtaining the point (0,3) which is not true for the function f(x) shown in the graph.

2) For f(5)=-1 the input value is x=5 and the output value is y=-1, obtaining the point (5,-1) which is true for the function f(x) shown in the graph.

3) For f(3)=2 the input value is x=3 and the output value is y=2, obtaining the point (3,2) which is not    true for the function f(x) shown in the graph.

4) For f(2)=-2 the input value is x=2 and the output value is y=-2, obtaining the point (2,-2) which is not true for the function f(x) shown in the graph.

Helene is finding the sum (9 10i) (–8 11i). She rewrites the sum as (–8 11)i (9 10)i. Which statement explains the property of a
Andreyy89

She made the mistake of grouping unlike terms and factorizing.

Given that

Helene is finding the sum (9 + 10i) + (–8 + 11i).

She rewrites the sum as (–8 + 11)i + (9 + 10)i.

We have to determine

Which statement explains the property of addition that she made an error in using?

According to the question

The mistake she did is in the second term distributing.

(9+10i) is not equal to (9+10)i

Similarly (-8+11i) is not equal to (-8+11)i.

The correct method she should have done is given below;

Grouping real terms together and imaginary terms together and finding the sum is,

\rm =  (9 + 10i) + (-8 + 11i)\\\\= 9+10i-8+11i\\\\= (9-8) +(10i+11i)\\\\=1+21i

Hence, she made the mistake of grouping unlike terms and factorizing.

Answer:

  f(0) = 1/2

Step-by-step explanation:

At x=0, the inequality tells you ...

  1/2 ≤ 1 -f(0) ≤ 1/2

That is, ...

  1 - f(0) = 1/2

  f(0) = 1/2

  \boxed{\lim\limits_{x\to 0}{f(x)}=\dfrac{1}{2}}
