Answer:
6
Step-by-step explanation:
To find the x- intercept, suptitude in 0 for y and solve for x
If the base were 1, then the final value would never change...it would be a constant...
If the base is between zero and one, it is an exponential decay equation, so the final value would continually get smaller and smaller...
Can you please show something, I can not solve it without something to look at, but I believe the answer may be 28.
