Explanation:
The expression f(0) represents the value of the function at x=0 which means the y-intercept of the function.
the y-intercept of the graph is the point that crosses the y-axis.
From the given graph,
The y-intercept of the graph does not define.
Answer: f(0) = not defined
Answer:

Step-by-step explanation:
Given:

First, note that

So, the equation is

Multiply this equation by 

The general solution is

Anything smaller than 11.46. Decimal and whole number wise.
This is because it says Dan’s time was faster, meaning he took less time then Jake, thus making it so the time has to be smaller than 11.46.

The best estimate is:
D ) 3 meters.
You can eliminate the others as not making sense.
