Answer:
The key features of any function can be compared in tables and graphs by creating the matching graph for the function. Then, you can compare the different aspects of the graph. When you add a constant to an exponential graph, it will be translated up or down.

Answer:
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).
Answer:
Equation of parabola:
Step-by-step explanation:
A parabola with vertex (0,0), that opens to the right.
The general equation of parabola open right whose vertex (0,0)
Focal width : Two points opposite to the the focus on parabola.
Distance between these two points is called focal width i,e 4p
Focal width = 8
So, 4p=8
p=2
Focus: (2,0)
Equation of parabola:
Answer:
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y
