Answer: Choice B
{(0,0), (1,2), (2,4), (3,4)}
===============================================
Explanation:
A function is only possible if each x input leads to exactly one y output. For choice A, we have x = 1 lead to y = 3 and y = 5 at the same time, which is what the points (1,3) and (1,5) are saying. Therefore, choice A is not a function.
Choice C is also ruled out because x = 2 repeats itself as well. In this case, (2,3) and (2,4) means that the input x = 2 leads to the two outputs y = 3 and y = 4.
Choice D can be eliminated also for two reasons: x = 0 shows up twice, so does x = 2.
Only choice B has each x value listed one time only. So that means each input leads to exactly one output.
If you graph choice A, C or D, you'll find they fail the vertical line test. The vertical line test is where you test if you can draw a vertical line through more than one point on the graph. If you can draw a vertical line through more than one point on the graph, then the relation fails to be a function.
Answer: 123
Step-by-step explanation:
Graph will look like this if this is one of the options
15m ^3 - 26m^2 +11m - 4 is the result of the product.
(5m^2 -2m +1)(3m-4)
On opening the bracket, we multiply the terms,
= 15m^3 -6m^2 +3m -20m^2+8m -4
= 15m ^3 - 26m^2 +11m - 4
This is the result of the product
When we mutiply the two equations.
Answer:
By plus 2 points
Step-by-step explanation:
The median average is the midpoint in a list of acceding values, in this case the median is 16,18,<em>20</em>,24,28 so its 20. But after they score 30 points in their next game, the median will be 16,18,<em>20</em>,<em>24</em>,28,30. Since there is 2 midpoints we have to take the mean average of both, which is just adding up the value of all terms and then dividing by the number of terms in the list.
(20+24)/2 = 22
Our median average before the sixth game is 20 and after its 22, do the change in median is +2
