The function y=4(5/6)ˣ is an exponential decay with a y intercept of 4.
What is an exponential function?
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
If b > 1, this is an exponential growth and if b < 1, this is an exponential decay.
Given the function:
y=4(5/6)ˣ
The y intercept is at x = 0:
5/6 < 1
y=4(5/6)⁰ = 4
The function y=4(5/6)ˣ is an exponential decay with a y intercept of 4.
