Well what is 30x3 (because that is how you would find what is one third of unknown) then you find the answer witch is 90$
3/12 + 10/12 = 13/12 because the points lie in-between the 1/6 and 2/6 marks and the 6/6 and 7/6 marks.
The answer for this is 10
Answer:
See explanation
Step-by-step explanation:
Given the function f(x) for which
![\begin{array}{ccccc}x&-4&0&3&7\\ \\f(x)&9&5&2&-2\end {array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccccc%7Dx%26-4%260%263%267%5C%5C%20%5C%5Cf%28x%29%269%265%262%26-2%5Cend%20%7Barray%7D)
If you want to plot the corresponding points for the inverse of the function f(x), change
into
:
![\begin{array}{ccccc}x&-4&0&3&7\\ \\y&9&5&2&-2\end {array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccccc%7Dx%26-4%260%263%267%5C%5C%20%5C%5Cy%269%265%262%26-2%5Cend%20%7Barray%7D)
switch x and y
![\begin{array}{ccccc}y&-4&0&3&7\\ \\x&9&5&2&-2\end {array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccccc%7Dy%26-4%260%263%267%5C%5C%20%5C%5Cx%269%265%262%26-2%5Cend%20%7Barray%7D)
and then change
into
You get
![\begin{array}{ccccc}x&9&5&2&-2\\ \\f^{-1}(x)&-4&0&3&7\end {array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccccc%7Dx%269%265%262%26-2%5C%5C%20%5C%5Cf%5E%7B-1%7D%28x%29%26-4%260%263%267%5Cend%20%7Barray%7D)
Now plot these points on the coordinate plane (see attached diagram).
