Given the function f(x)=x2+2x+1, find: f(2b)

pashok25 [27]

I will do the first one only. The second question is done the same way.

Replace every x you see in the function with 2b and do the math.

f(x) = x^2 + 2x + 1

Let x = 2b

f(2b) = (2b)^2 + 2(2b) + 1

f(2b) = 4b^2 + 4b + 1

Did you follow? That's all there is to it.

What is 1/10 + 50/100?

erastovalidia [21]

Answer:

$\large\boxed{\dfrac{3}{5}=0.6}$

Step-by-step explanation:

$\bold{METHOD\ 1:}\\\\\dfrac{1}{10}+\dfrac{50}{100}=\dfrac{1}{10}+\dfrac{50\!\!\!\!\diagup}{100\!\!\!\!\diagup}=\dfrac{1}{10}+\dfrac{5}{10}=\dfrac{1+5}{10}=\dfrac{6}{10}=\dfrac{6:2}{10:2}=\dfrac{3}{5}\\\\\bold{METHOD\ 2:}\\\\\text{Convert the fractions to decimal:}\\\\\dfrac{1}{10}=0.1\\\\\dfrac{50}{100}=0.50=0.5\\\\\dfrac{1}{10}+\dfrac{50}{100}=0.1+0.5=0.6$

$f(x)=13|x-5|-6$ is the equation represented by all the operations.

Step-by-step explanation:

The given function is

$f(x)=|x|$

It is vertically compressed by a factor of 13 then the function becomes,

$f(x)=13|x|$

It shifted down 6 units, then the function becomes,

$\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}$

It shifted right by 5 units then the function becomes,

$f(x)=13|x-5|-6$

Thus the resultant equation thus obtained is $f(x)=13|x-5|-6$
