Recursive equation would be f(x+1) = f(x) - 25 with f(0) = 300
Explicit equation would be f(x) = -25x + 300
And graph would looks like this:
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
Answer:
d = 244
Step-by-step explanation:

Where r is the radius of the circle.
Answer: B
The piece wise functions first part says: x is less than it equal to one and has a vertical shift down 4. which would mean the circle is closed and shaded down.
The second part of the function says x is greater than one and has a vertical shift up 3. This would mean it is an open circle and is shaded up.
