Answer:
In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.
Step-by-step explanation:
<u>Substitute f(0) into the function:</u>

<u>Include exponent:</u>

<u>Multiply:</u>

Sorry this is really sloppy but hope this helps!
Answer:y=-3
Step-by-step explanation:yes firs multiply everything by -3 in parenthesies
Then you would subtract 15 from both sides
Next you would divide 9 by -3 and you would get -3
So y =-3
Consider a right triangle in which one of the angles
satisfies

That is, the side opposite
occurs in a ratio of 3 to 5 with the hypotenuse. The side adjacent to
then occurs in a ratio of 4 to 5 with the hypotenuse. In other words,

because

Then in this triangle,
