Which relation is a function?

Mathematics
1 answer:
NARA [144]1 year ago
8 0

Answer:

A function means that we get one input and one output.  In this example that means for every x-value that we have, we only have one y-value.

Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.

The rest of the options are seen with at least two values for one x-value in one of the points.  Therefore, they wouldn't be considered a function leaving us with only option A as the solution.

What is the equation of a circle with center (-4,7) radius 3?
miv72 [106K]

Answer:

a. (x + 4)² + (y – 7)² = 3²

Step-by-step explanation:

General equation for a circle is:

(x – h)² + (y – k)² = r²

h and k are the center (h, k), and r is the radius.

They want a center of (-4, 7) so h=-4 and k=7

They want a radius of 3 so r=3

plug it into the equation.

(x – h)² + (y – k)² = r²

(x – (-4))² + (y – (7))² = (3)²

(x + 4)² + (y – 7)² = 3²

For what value of X is the rational expression below equal to zero?
Sophie [7]

Answer:

Option D, x = 1

Step-by-step explanation:

In order for that equation to equal to zero, you need the numerator (the top) to equal zero and the denominator (the bottom) to equal literally anything BUT ZERO.

To satisfy the first part we set the top binomial equal to zero.

x - 1 = 0

x = 0 + 1

x = 1

Plug in x = 1 to the bottom to see if it satisfies to second part; we're looking for everything but zero.

(x - 3)(x + 1)

(1 - 3)(1 + 1)

(- 2)(2) = - 4

Your answer is x = 1, option D.
