​f: initial value of 400 decreasing at a rate of 14​%
​g: initial value of 30 increasing at a rate of 14​%

Write the exponential function for f.

f(x)=400(0.86)^x

Write the exponential function for g.

g(x)=30(1.14)^x

The value of x that makes ​f(x)=(x) is x=___.
​(Round to the nearest integer as​ needed.)
