Answer:

Yes, it is. Functions can only have one output (y) for each input (x). Furthermore, this means each x value will only have one y passing through it. Thus if we plot it on a graph and it passes through a horizontal line more than once, it is not a function. This is called the vertical line test.

Your friend has built the skate board ramp shown in the figure with sides of 16 in., 63 in., and 65 in. that he claims has dispr
nexus9112 [7]
The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then  c^{2} = a^{2}  +  b^{2} 
if c=65 inches, a=16 inches and b = 63 inches, then
 65^{2} =16 ^{2} +  63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.
