## anonymous one year ago Which of the following equations best represents the graph of a function f(m)? (1 point) f(y) = m f(x) = m y = f(m) x = f(m)

1. anonymous

Pleas help will fan and medal the person who explains it and gives me the answer!

2. anonymous

3. anonymous

y = f(m)

4. anonymous

y = a function of m

Ok thanks can you help me with some more?

6. anonymous

sure one more

If f(x) = 7x - 1, what does f(12) represent? The value if x when (7x - 1) = 12 The value of (7x - 1) when x = 12 The value of 12 f(x) when x = 12 The value of f(x) when (7x - 1) = 12

8. anonymous

plug in 12 for x

9. anonymous

The value of (7x - 1) when x = 12

10. anonymous

So B?

11. anonymous

f(x) F(12) x=12

12. anonymous

13. anonymous

But deeezzzz is correct

14. anonymous

If f(x) = 2x2 - 10, find f(5). 90 10 7.5 40 Last one haha

15. anonymous

Plug in 5 for x

Mkay...

17. anonymous

f(5) is essentially f(5)=(2x5)^2 -10

18. anonymous

Mkay.... so it would be C?

19. anonymous

uh....nooo... Is that a 2x^2 btw? just checking

20. anonymous

2x with a 2 has the exponent

21. anonymous

so $f(x)=2x^2-10$

22. anonymous

Yep

23. anonymous

then $f(5)=(2\times5)^2-10$

24. anonymous

Ohh wait a moment would it be A?

25. anonymous

$f(5)=(10)^2-10$

26. anonymous

YES Correct!!!

27. anonymous

Ok thanks so much!!!

If f(x) is the height, in cm, of a sunflower plant which is x days old, which of the following statements best describes the meaning of f(60) = 210? The height of the sunflower plant is 60 cm when it is 210 days old. The height of the sunflower plant is 210 cm when it is 60 days old. The height of the sunflower plant is 210 cm when it is 3.5 days old. The height of the sunflower plant is 60 cm when it is 3.5 days old.
