According to the given plot, . Then the linear approximation to
at
is
Then
On the interval [0, 1], the plot of is positive, so
is an increasing function here. But we can see that
is approaching 0. This means tangent lines to
have a positive slope, but the slopes are approaching 0 and are thus becoming less steep. This in turn means the tangent lines lie above the curve, so the approximations are greater than the actual values of
and
.
Answer:
See explanation
Step-by-step explanation:
This question requires a list of options.
Since, there are none; I'll give a general explanation to answer this.
We have that:
The general format of an equation in terms of f and c is:
Where
and
A true statement about the function above is:
The slope of the equation is 14
This means that at every minute, there's an additional 14 chirps from the cricket.
Another true statement about the function is that:
The y intercept is 40.
This means that the initial number of chirps by the cricket is 40
i.e. At time, c = 0 minutes.
There are 40 chirps.
A likely question could be to determine the number of chirps in (say) 5 minutes.
This means that:
Substitute 5 for c in
This implies there are 110 chirps in 5 minutes
