Answer:

See the attached file.

Step-by-step explanation:

The given base function is

$f(x) = \sqrt{x}$

The transformed function has equation.

$g(x) = - \sqrt{x - 3} + 11$

The -1 in front of the radical reflects f over the x-axis.

The 3 under the radical sign shifts the graph of f to the right by 3 units.

The 11 shifts the graph up by 11 units.

Alexandra [31]

Answer:

Difference in scores between his 7th and 8th quizzes = 22

Step-by-step explanation:

Given: Mean score for first 6 quizzes is 33 points. After his 7th quiz his mean score was 32 points. After the 8th quiz the mean was 34.

To find: difference in scores between his 7th and 8th quizzes

Solution:

Mean scores = Total points scored in quizzes ÷ Number of quizzes

So,

Total points scored in quizzes = Mean scores × Number of quizzes

As mean score for first 6 quizzes is 33 points,

Total points scored in 6 quizzes = 6 × 33 = 198

As mean score for first 7 quizzes is 32 points,

Total points scored in 7 quizzes = 7 × 32 = 224

So,

7th score = Total points scored in 7 quizzes - Total points scored in 6 quizzes

= 224 - 198

= 26

As mean score for first 8 quizzes is 34 points,

Total points scored in 8 quizzes = 8 × 34 = 272

So,

8th score = Total points scored in 8 quizzes - Total points scored in 7 quizzes

= 272 - 224

= 48

Therefore,

Difference in scores between his 7th and 8th quizzes = 48 - 26

= 22
