For the given statement Pn, write the statements P1, Pk, and Pk+1.
Leno4ka [110]

Answer:

P_{1} =  2

P_{k} = k(k+1)

P_{k+1} = (k+1)(k+2)

Step-by-step explanation:

We are given the statement,

P_{n} as 2 + 4 + 6 + . . . + 2n = n(n+1)

That is,

P_{n} as 2 + 4 + 6 + . . . + 2n = \sum_{i=1}^{n}2i

So, we have,

P_{1} = \sum_{i=1}^{1}2i = 2

P_{k} = \sum_{i=1}^{k}2i = 2 + 4 + 6 + . . . + 2k = k(k+1)

P_{k+1} = \sum_{i=1}^{k}2i = 2 + 4 + 6 + . . . + 2k + 2(k+1) = (k+1)(k+2)

Thus, we get,

P_{1} =  2

P_{k} = k(k+1)

P_{k+1} = (k+1)(k+2)

Consider the function f(x) = √5x + 15 for the domain [-3, ∞).Find f-¹(x), where f-1 is the inverse of f.Also state the domain of
Ymorist [56]

Answer: We have to find the inverse function of the following:

f(x)=\sqrt{5x+15}\rightarrow[-3,\infty)\Rightarrow(1)

The Inverse of the (1) is as follows:

\begin{gathered} f(x)=y=\sqrt{5x+15} \\  \\ \text{ Switch: }x\text{  and }y\text{ and solve for }y(x)\text{ } \\  \\  \\ y=\sqrt{5x+15}\rightarrow x=\sqrt{5y+15} \\  \\  \\ x^2=5y+15 \\  \\  \\ x^2-15=5y \\  \\  \\ y=\frac{x^2}{5}-\frac{15}{5} \\  \\  \\  \\ y=f^{-1}(x)=\frac{x^2}{5}-3 \\  \\  \\ f^{-1}(x)=\frac{x^{2}}{5}-3 \end{gathered}

The domain of the inverse function is:

x\in(-\infty,+\infty)
