Find the common ratio geometric sequence please
Rudiy27
Recall that in a geometric sequence, you multiply the "current" one by the common ratio to get the "next" so, if you divide "next"/"current", the quotient is just the common ratio,

\bf \cfrac{27}{243}=\cfrac{3}{27}=\cfrac{\frac{1}{3}}{3}=\cfrac{\frac{1}{27}}{\frac{1}{3}}\implies \cfrac{1}{9}\impliedby \textit{common ratio}

notice, all we did was, divide the value, by the number to its left-hand-side.

I need help on this plzzz I and not the best at math ​
vampirchik [111]

Answer:

See attachment for graph

<em></em>

Step-by-step explanation:

Given

f(x) = \left[\begin{array}{cc}-1&x1\end{array}\right

Required

The graph of the step function

Before plotting the graph, it should be noted that:

\le and \ge use closed circle at its end

and > use open circle at its end

So, we have:

f(x) = -1,\ \ \ \ x < -1

The line stops at -1 with an open circle      

f(x) = 0,\ \ \ \ -1 \le x \le 1

The line starts at - 1 and stops at -1 with a closed circle at both ends

f(x) = 1,\ \ \ \ x > 1

The line starts at 1 with an open circle

The options are not complete, so I will plot the graph myself.
