The exponential function that shows San Francisco area after x years is y = 49(0.98)ˣ
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let y represent the land area of San Francisco after x years. Hence:
The city is only about 49 square miles in area, a = 49. It is losing 2% yearly, hence b = 100% - 2% = 0.98
The equation becomes y = 49(0.98)ˣ

Answer:
It's C
Step-by-step explanation:
I believe my calculations are correct
For number one the answer is: X = 30
For number two the answer is: All real numbers are solutions.
For number three the answer is: There are no solutions.
The slope is going from left to right instead of right to lift.(opposite direction)
