Is x^2+y^2=5 a function? why or why not?

Mathematics
1 answer:
ZanzabumX [31]3 years ago

Answer:

No.

Step-by-step explanation:

A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is <em>not</em> a function.

We can see this using a graph:

Since the vertical line test passes 2 points with the same x-value, it is not a function.

A triangle has sides with lengths of 18 centimeters, 68 centimeters and 74 centimeters. Is it a right triangle?
Hoochie [10]
18^2 + 68^2 =

= 324 + 4,624

= 4,948

74^2 = 5,476

4,848 is not equal to 5,476.

Since the sum of the squares of the lengths of the two shorter sides is not equal to the square of the length of the longest side, the triangle is not a right triangle.
