3 1/3 I presume because 1 + 3 is 4 and 8 + 4 is 12. 4/12 into.simplest form is 1/3.
Reflection across the origin did not take place here.
The area of the cylinder is a function of its height (h) and radius, ()
The exact value of h is:
The given parameters are:
The surface area of a cylinder is calculated as:
Substitute values for Area
Divide through by pi
Substitute value for r
Collect like terms
Make h the subject
Rationalize
Hence, the exact value of h is:

1. Functions of the form f(x)=ax+b, where a is non zero, are called "linear functions" and the graphs of them are inclined lines.
2. If a>0, the line is increasing, so it gets higher as we move x to the right
If a<0, the line is decreasing.
3. There is no x we are not allowed to plug in the function: so Domain = all Real numbers
4. Since the lines are either increasing or decreasing, f(x), represented by the y values, take all values from -∞ to +∞. So Range = all Real numbers.
f(x)=4x (increasing line, 4>0) ,
g(x)=-x+4, h(x)=-4x (decreasing lines, -1<0, -4<0)
all f, g, h have Domain AND Range : All real numbers
First focus on the parentheses. Distribute the 3 by multiplying by x and -4.
8 + 3(x-4) = 8 + 3x -12
Then, combine like terms (things with x, things without an x, the 8 and -12)
=3x - 4
