State the domain and range of the relation { (-3,2),(4,1)(0.3),(5,2),(2,7)} .Then determine whether the relation is a function.

1 answer:

6 0

Answer:

Domain: {-3, 0, 2, 4, 5)
Range: {1, 2, 3, 7}

The relation is a function because for every x-value there is one y-value. In other words, for every input there is one output.

The answer would be C. What you will do is use the Midpoint formula. (x1+x2/2, y1+y2/2).
Hope this helps! (:

What is the percent of increase from 40.2 to 98.9?

alekssr [168]

Answer:

146%

Step-by-step explanation:

To find the percent increase/decrease:

1. Subtract the original value from the new value.

2. Divide by the original value.

3. Multiply the decimal by 100 to convert to a percent.

98.9 - 40.2 = 58.7

58.7/40.2 = 1.46

1.46*100 = 146%

This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
