f(x) = 4x + 3

That's one-to-one, a linear function that will give a different f(x) for each different x.

For the inverse let's swap x and y and solve for y

x = 4y + 3

x - 3 = 4y

y = (x- 3)/4

That's the inverse,

Answer:  (x- 3)/4, second choice

The domain and range of the inverse is all real numbers.  It's two lines; I'll leave the graphing to you.

What is the five number summary for the data 0,2,2,4,5,5,5,5,7,11
salantis [7]

The five number summary data for the data-set is:

  • Smallest value: 0.
  • First quartile: 2.
  • Median: 5.
  • Third quartile: 6.
  • Greatest value: 11.

<h3>What is the five number summary of a data-set?</h3>

The five number summary of a data-set is composed by:

  • The smallest and the greatest value.
  • The first quartile, which is the median of the bottom 50%.
  • The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
  • The third quartile, which is the median of the upper 50%.

For this problem, we have that:

  • The smallest value is of 0.
  • The greatest value is of 11.

The data-set has 10 elements, which is an even cardinality, hence the median is the <u>mean of the 5th and the 6th elements</u>, hence:

Me = (5 + 5)/2 = 5.

The first half of the data-set is:

0, 2, 2, 4.

Hence the first quartile is:

Q1 = (2 + 2)/2 = 2.

The second half of the data-set is:

5,5,7,11.

Hence the third quartile is:

Q3 = (5 + 7)/2 = 6.
