Step-by-step explanation:
-Equation of a circle is:
where the center is (h, k) and the radius is
.
-Place the center and the point onto that equation:
-Then, you solve:
-So, the result is:

Answer:
y = 16
Step-by-step explanation:
Use the given points to find the values of a and b
Using (0, 16), then
16 = a (
= 1 ), thus
a = 16
y = 16
Using (2, 400), then
400 = 16b² ( divide both sides by 16 )
b² = 25 ( take the square root of both sides )
b = = 5
Thus
y = 16 × ← exponential function
