For this case we have that the main function is given by:
We apply the following transformations:
Vertical expansions:
To graph y = a * f (x)
If a> 1, the graph of y = f (x) is expanded vertically by a factor a.
For a = 5 we have:
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
For k = 5 we have:
Answer:
The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.
The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is:
<u><em>Explanation</em></u>
Number of right answers is and number of wrong answers is
Olga earns 12 points for each right answer and loses 4 points for each wrong answer.
So, total points earned for right answers
and total points lost for wrong answers
That means, <u>her score will be</u>: points.
In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......
