Answer:
7/12
Step-by-step explanation:
1/3 or seven 7/12?
First find the common denominator, in this case 12
1/3 x 4 = 4/12
4/12 or 7/12?
7/12 is greater!
K(x) = (1/2)ˣ
Since a (=1/2) is < 1, this exponential function is decreasing .
y-intercept for x = 0
k(x) =(1/2)⁰ → k(x) =1, then y-intercept = 1
Horizontal Asymptote:
lim k(x) = (1/2)ˣ = 0
x→∞
Horizontal asymptote x = 0
The radius of the circle is

, which is 4
The center of the circle is at (0,10)
