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.

Using mathematical induction prove whether or not the following statement is true for all positive integers n, or show why it is

aniked [119]

Base case: For $n=1$ , the left side is 2 and the right is $2\cdot1^2=2$ , so the base case holds.

Induction hypothesis: Assume the statement is true for $n=k$ , that is

$2+6+10+\cdots+4k-2=2k^2$

We want to show that this implies truth for $n=k+1$ , that

$2+6+10+\cdots+4k-2+4(k+1)-2=2(k+1)^2$

The first $k$ terms on the left reduce according to the assumption above, and we can simplify the $k+1$ -th term a bit:

$\underbrace{2+6+10+\cdots+4k-2}_{2k^2}+4k+2$

$2k^2+4k+2=2(k^2+2k+1)=2(k+1)^2$

so the statement is true for all $n\in\mathbb N$ .
