Which of the following lists of orders pairs is a funtion
nordsb [41]

Answer:

D


Step-by-step explanation:

For it to be a function, every x value must have 1 unique y value ONLY.


In option A, you can see that the x value of 1 has 2 y values, 1 & 5. So it's not a function.


In option B, you can see that the x value of 0 has 2 y values, 0 & -4. Moreover, the x value of 4 also has 2 y values, 2 & -2. So it's not a function.


In option C, you can see that the x value of -2 has 2 y values, 4 & -4. This is not a function as well.


In option D, each x value has a unique y value that are different. So this is a function.


Answer is option D.

HELP!!! Which graph best shows the function f(x) = 4(3)−x to represent the rate at which a radioactive substance decays?​
bagirrra123 [75]

Answer:

B

Step-by-step explanation:

The exponential function has the form y = a(b^x) where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, y = 4(3^{-x}) has starting value 4, rate 3 and a -x.

Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.

Please help. Thank you!
Makovka662 [10]

Answer: See explanation

Step-by-step explanation:

By the Triangle Inequality Theorem, the length of the side must be greater than 1 ft because the sum of two side lengths must be greater than the length of the third side. The third side must be less than 7 ft but greater than 1 ft.

Triangle inequality: 1 < x < 7

Hope that helped!
