Answer: There is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.
Step-by-step explanation: The (x-3) shifts the graph three units right, think of as for (x)=0 x has to be 0, and for (x-3)=0 x has to be 3, which is 0+3. The vertical stretch multiplies everything by 2, so it should make sense that it's a vertical stretch by a factor of 2.

Answer:
the center is (3,1) and the radius is √6.
Step-by-step explanation:
The center of a circle can be found using the equation 
and is (h,k) from it. Notice h and k are the opposite value as in the equation.
First write the equation in this form.
Complete the square with each variable to find what numbers should go in place of the question marks.
Add 1 and 9 to both sides of the equation.
So the center is (3,1) and the radius is √6.
Answer:
-2 2/5
Step-by-step explanation:
-3 4/5 = 19/5
1 2/5 = 7/5
-19/5 + 7/5 = -12/5
-12/5 = -2 2/5 = -2.4
