# Question #5dd43

Jan 25, 2018

Here's four values of $x$ and what you get when you plug them into $B \left(x\right)$:

$\textcolor{w h i t e}{\text{....." x color(white)"---------" B(x)}}$
$\text{------------------------}$
$\textcolor{w h i t e}{\text{.." -2 color(white)"----------}} 19$
$\textcolor{w h i t e}{\text{....." 0 color(white)"------.....}} 18$
$\textcolor{w h i t e}{\text{.--"55 color(white)"-----...}} - 9.5$
$\textcolor{w h i t e}{\text{--"5.5 color(white)"--------..}} 15.25$

#### Explanation:

I am not quite sure what is being asked, but I will try my best to respond in a way that answers any questions you may have.

The function you gave is:

$B \left(x\right) = 18 - 0.5 x$

I believe you need to find the value of the function for different values of $x$.

You listed $- 2 , 0 ,$and $55$, which I believe may be a typo of $5.5$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can find the value of $B \left(x\right)$ for a certain $x$ value by substituting the other number for $x$ in the equation.

After all, the function $B \left(x\right)$ is just a set of instructions for what to do with $x$ to get the value you want.

So, let's plug in some numbers and see what we get:

$B \left(\textcolor{red}{- 2}\right) = 18 - 0.5 \left(\textcolor{red}{- 2}\right) = 18 + 1 = 19$

$B \left(\textcolor{b l u e}{0}\right) = 18 - 0.5 \left(\textcolor{b l u e}{0}\right) = 18 + 0 = 18$

$B \left(\textcolor{\mathmr{and} a n \ge}{55}\right) = 18 - 0.5 \left(\textcolor{\mathmr{and} a n \ge}{55}\right) = 18 - 27.5 = - 9.5$

$B \left(\textcolor{\lim e g r e e n}{5.5}\right) = 18 - 0.5 \left(\textcolor{\lim e g r e e n}{5.5}\right) = 18 - 2.75 = 15.25$

So there's four values of $B \left(x\right)$ and how we got them!

Again, you may not need all of this information, or this may be exactly what you were looking for. However, if this isn't what you were asking for, please respond so I can answer any other questions you may have. I would be happy to help you with anything else you need!

Hope this helps!
