Answer:
In this equation, the y-intercept (+ 5) represents the original height of the plant. 2x represents the amount of growth multiplied by the number of days, x.
Step-by-step explanation:
The <em><u>correct answer</u></em> is:

Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us

2:3 is equivalent to 0.666 repeating
