Answer:
it has two line
Step-by-step explanation:
Answer:
<em><u>The answer is m(x) </u></em><em><u>= -7x =</u></em><em><u>A function will only have an inverse function if the function is one-to-one. If you graph the function out and it passes the horizontal line test, it is one-to-one. Only the function m(x) = -7x will have an inverse that is a function. The graph of y = m(x) is a linear function. Linear functions pass the horizontal line test (it's symmetric about the y-axis). The function does not have an inverse that is a function because the graph of b(x) is parabolic. It will fail the horizontal line test when you graph it out. The function does not have an inverse that is a function because the graph of d(x) is a horizontal line. A horizontal line fails the horizontal line test because it is a horizontal line. The function does not have an inverse that is a function because the graph of p(x) fails the horizontal line test (it's symmetric about the y-axis).</u></em>
So one key thing to remember here is that the direction of the correlation is irrelevant, that is it does not matter if your correlation is + or - what matters is how close that number is to 1.0.
To help you out here are the ranges of correlation strength
- 0.70. A strong relationship
- 0.50. A moderate relationship
- 0.30. A weak relationship
So to start off with 0.26 and 0.18 are very small correlations so you'd call those weak correlations.
Let me know if you need help doing the other ones? It should be simple enough with the data I gave you :)
Be more specific. Like what is it asking you to do ? I'm trying to help. :)
