## queenie251 2 years ago Beth is a photographer taking pictures outdoors during the evening. She knows that the later it is when she takes a picture, the longer the shutter has to stay open to get enough light for the picture. A. The length of time the shutter needs to stay open is a function of how strong her flash is. B. How late it is in the evening is a function of the length of time the shutter needs to stay open. C. The length of time the shutter needs to stay open is a function of how late in the evening it is.

B

2. GaLm

thats the one that makes since

@GaLm does the light of the night depend on the shutter speed or the shutter speed depend of the light conditions? :)

4. GaLm

hmmm. i hate word problems. the shutter speed depend of the light conditions.

5. mathmate

Cool it guys. We're just solving a problem here! @queenie251 you get your answer now?

6. GaLm

yea its: the shutter speed depend of the light conditions

7. mathmate

Guys, please stay on topic, or else it becomes an abuse.

8. GaLm

yea he stopped. sorry. but the answer is: the shutter speed depend of the light conditions

9. GaLm

wait. but in the question. what does it mean what it says function? as in "its a factor of"?

10. mathmate

" a function of" means it "depends on" Example: when you go to the grocery store, the total bill at check-out is "a function of" what you bought.

11. mathmate

Mathematically, it is expressed as: f(x) means function f is a function of x (the independent variable). x is usually plotted on the x-axis.

12. GaLm

ok . so its C sorry :)

13. mathmate

Sounds good to me! :)

14. GaLm

ok good :). i just reallized this question was clossed. but whatever. i GTG thanks for the help!

15. mathmate

yw! :)
