Composition functions are functions in which the input goes in and the output of the first function becomes the input for the second. You can evaluate these in two ways.
1) You can simply input the x value into the first function. After solving for it's value, you can input into the second one. The output is the composite functions answer.
2) If they only want a new function or you want to do it a different way, you have to put the first function (the whole thing) in for x in every place. You can then simplify.
the answer is D hope helps did before
The answer is 13/4 3.25 is equal to 13/4
Given:
Figures A, B and C.
To find:
The order of the figures and volume of each figure.
Solution:
<u>Figure A:</u>
Length = 10, Width = 2 and Height = 2
Volume of A = length × width × height
= 10 × 2 × 2
Volume of A = 40 cubic units
<u>Figure B:</u>
Length = 3, Width = 3 and Height = 1
Volume of B = length × width × height
= 3 × 3 × 1
Volume of B = 9 cubic units
<u>Figure C:</u>
Length = 6, Width = 3 and Height = 3
Volume of C = length × width × height
= 6 × 3 × 3
Volume of C = 54 cubic units
Order from greatest to least:
54 < 40 < 9
C < A < B
Hence Kurry said the correct answer.
