1. 8
2. square of 7
3. 1/2
4. 20
Let’s rethink the question with functions. If f(x) = y then y should be changing by the value of x.
The cross section that results, is a triangle.
Step-by-step explanation:
Cross section is a shape that forms when a slice or a cut is made through a solid.
A solid can have multiple cross sections depending on where you slice the solid.
Cross section perpendicular to the base of a solid will result in triangles.Cross sections parallel to the base of the solid will result in hexagons and so on.
Cross section help in representing three dimension objects in a two dimension way.
How To Find Inverses:
1. First, replace f(x) with y . ...
2. Replace every x with a y and replace every y with an x .
3. Solve the equation from Step 2 for y . ...
4. Replace y with f−1(x) f − 1 ( x ) . ...
5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
