4 + 12 +12 = 28cm
so in conclusion it is 28
No, a parallelogram is not a rectangle. meaning it has a completely different area formula, I know it sucks.
Formula: base × height
I don't use feet and inches. sorry I couldn't provide with to much help.
Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
When a function is reflected, it must be reflected over a line
The new function is: 
The equation is given as:

The rule of reflection over the y-axis is:

So, we have:

Rewrite as:

Hence, the new function is:
