To tell if it is not a function you do a vertical line test. A vertical line test is when you draw a vertical line to test if the ordered pairs are a function or not.If the vertical line intersects the plotted points once it is a function and if the vertical line intersects the plotted points more than once it is not a function. An example of ordered pairs that are not a function is (2,6) and (2,8).
Well the first one is obtuse and more than 90 degrees, the 2nd one is also obtuse and more than 90 degrees, the 3rd one is acute and less than 90 degrees, the 4th one is obtuse and 180 degrees, and the 5th one is a right angle and is 90 degrees

Answer: True
Solution:
Rearrange the equation to the LHS:
[x^2 + 8x + 16] · [x^2 – 8x + 16] - (x^2 – 16)^2 = 0
Factoring x^2+8x+16
x^2 - 4x - 4x - 16
= (x-4) • (x-4)
= = (x+4)2
So now we have an equation
(x + 4)^2 • (x - 4)^2 - (x^2 - 16)^2 = 0
Step 2: Evaluate the following:
(x+4)2 = x^2+8x+16
(x-4)2 = x^2-8x+16
(x^2-16)2 = x^4-32x^2+256
(x^2+8x+16) (x^2-8x+16 ) - (x^4-32x^2+256 )
0 = 0
Hence True
