Answer:

6(2b-4)

=12b-24

Step-by-step explanation:

You distribute the six into both numbers inside the parentheses by multiplying.

Distribute

6 × 2b + 6 × -4

Simplify 6 × 2b to 12b

12b + 6 × -4

Simplify 6 × -4 to -24

<u>12b - 24</u>

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

f(x) =  {x}^{2}  + 2x

For f( - 3), substitute "-3" for each occurrence of "x".

f( - 3) = ( { - 3})^{2}  + 2( - 3)

= ( - 3 \times  - 3) - 6

= 9 - 6

= 3

If f (n)(0) = (n + 1)! for n = 0, 1, 2, , find the taylor series at a=0 for f.
Pie
Given that f^{(n)}(0)=(n+1)!, we have for f(x) the Taylor series expansion about 0 as

f(x)=\displaystyle\sum_{n=0}^\infty\frac{(n+1)!}{n!}x^n=\sum_{n=0}^\infty(n+1)x^n

Replace n+1 with n, so that the series is equivalent to

f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}

and notice that

\displaystyle\frac{\mathrm d}{\mathrm dx}\sum_{n=0}^\infty x^n=\sum_{n=1}^\infty nx^{n-1}

Recall that for |x|, we have

\displaystyle\sum_{n=0}^\infty x^n=\frac1{1-x}

which means

f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}=\frac{\mathrm d}{\mathrm dx}\frac1{1-x}
\implies f(x)=\dfrac1{(1-x)^2}
