Part 1) The first four terms of a sequence are shown below.
Let
we know that
So
therefore
the answer part 1) is the option
Part 2) Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) + 20?
Let
(a,b)--------->represent a point in the graph of f(x)
we know that
In the new function f(x)+d
(a,b)-----------> become-------> (a,b+d)
So
The new function f(x)+d shift up by d
therefore
in the new function -------> the graph of f(x) shift up by
the answer part 2) is the option
The graph of y = f(x) will shift up units.
Part 3) Every week Annie plants 2 saplings in her garden. The function below shows the total number of saplings f(w) in her garden after w weeks.
we know that
The y-intercept is when the value of w is equal to zero
the value of f(w) for
represent the original number of saplings in Annie's garden
so
For
therefore
the answer is the option
It is equal to and represents the original number of saplings in Annie's garden.
