Answer:
(0,1) and (-2,9)
Step-by-step explanation:
A point (x,y) lies on the graph of f(x) = if it satisfies the condition y =
x = 0 and y = 1.
This point satisfies the required condition as
= 1
Hence, this point <u>is</u> on the graph of f(x) =
x = 3 and y = 27.
This point doesn't satisfy the required condition as
=
≠ 27
Hence, this point i<u>s not</u> on the graph of f(x) =
x = -2 and y = 9.
This point satisfies the required condition as
=
= 9
Hence, this point <u>is</u> on the graph of f(x) =
x = -1 and y = .
This point satisfies the required condition as
y = =
= 3 ≠
Hence, this point <u>is not</u> on the graph of f(x) =
The equation for any circle centered at the origin with a radius r is the following:
By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.
Thus, r=5.
This makes the equation:
That should be your answer, let me know if this is confusing in any way.
