1. Marco and his two younger sisters would like to purchase a silver charm bracelet for their mother’s birthday. They went to the mall and found what they were looking for at Store A. In Store A, the bracelet without charms costs $85 and each charm costs $15.

B. What would be a reasonable domain for this function based on this scenario? Explain why this is a proper domain.

@amistre64 @Mertsj @SWAG @SolomonZelman please help

undeadknight26 (undeadknight26):

f(x) = 15x + 85

OpenStudy (solomonzelman):

I suck at math, but do you see the problem? Can you write it out?

OpenStudy (solomonzelman):

yes! you know this staff!

undeadknight26 (undeadknight26):

haha me too...i have a horrible grade...

OpenStudy (solomonzelman):

that was quick.....! SMART!!!!

OpenStudy (solomonzelman):

you know why it is 15x, right?

undeadknight26 (undeadknight26):

The x axis?

undeadknight26 (undeadknight26):

oh no wait you have to plug in 0 to do something right?

undeadknight26 (undeadknight26):

i tried this and i don;t get what it is telling me. http://www.wolframalpha.com/input/?i=f%28x%29+%3D+15x+%2B+85

undeadknight26 (undeadknight26):

@SolomonZelman thanks for comming back! I still need to find the answer...

OpenStudy (solomonzelman):

try this link https://www.google.com/search?q=graph+f(x)+%3D+15x+%2B+85&aq=f&oq=graph+f(x)+%3D+15x+%2B+85&aqs=chrome.0.57.3327&sourceid=chrome&ie=UTF-8 you can understand the graph if you find (0,85) on it.

undeadknight26 (undeadknight26):

so the answer would be 1?

OpenStudy (solomonzelman):

how do you know that? explain!

undeadknight26 (undeadknight26):

Because u said to find 85 on the graph and it was at 1...well .05...

OpenStudy (solomonzelman):

will brake this down, you know what domain means right?

undeadknight26 (undeadknight26):

Yes the input or the x axis right?

OpenStudy (solomonzelman):

yes!

OpenStudy (solomonzelman):

I think that the answer is 0 (b/c the range is 85)

OpenStudy (solomonzelman):

(it does sound weird...)

undeadknight26 (undeadknight26):

yup...
