Answer:
Step-by-step explanation:
Here's a little known but very useful factoid:
If they're inversely proportional,
then their product is constant.
Here's how to use it:
-- We're told that Y = 8 when X = 7.
So when y=8 and x=7, their product is 56 .
-- If Y REALLY varies inversely as X, then
their product is ALWAYS going to be 56.
-- So when Y=4, X= (56/4) = 14 .
LnA +LnB= LnA.B
so we get <span>Log3(X-5)+log3(x+3)=Ln3(x-5)(x+3)=2 implies
</span>(x-5)(x+3)=2^3=8, so we can solve easily the quadratic equation
x^2-2x-23=0, there are two solution x=1 -sqrt(24), and x=1+sqrt(24)
Answer:
No, the graph does not represent a function because it does not pass the vertical line test.
<h2>What is a function?</h2>
A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.
<h3>Vertical Line Test</h3>
To pass the test, any vertical line that we draw on the graph should only touch one point.
A vertical line is a straight line that goes from top to bottom.
- Draw vertical lines through points on the graph, like in the photo below.
- Check if any vertical lines touch more than one point.
The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.
