Let f(x)= –2x + 4 and g(x) = –6x – 7. Find f(x)–g(x).

3. julliemyers

f(x) = 3x – 7 and g(x) = –2x – 6. Find (ƒ ∘ g)(4) What is the inverse of the given relation? y = 3x + 12

You square both sides of the equation so you get rid of the radical sign on the left.

Just x = 0

OH ok, can you help me with these? Let f(x)= –2x + 4 and g(x) = –6x – 7. Find f(x)–g(x). What is the inverse of the given relation? y = 3x + 12

@julliemyers What work have you done on these problems so far? It's hard to help out if I don't know what you already know and can do. :)

16. julliemyers

f(x) = 3x – 7 and g(x) = –2x – 6. Find (ƒ ∘ g)(4) (fo g)(4) f(g(4)) G(x)=-2x-6g(4)=-2*(4)-6g(4)=-8-6 g(4)=-14 f(g(4))=f(-14) f(x)=3x-7 f(-14)=3*(-14)-7 f(-14)=-42-7 f(-14)=-49 (f o g)(4)=-49

17. julliemyers

@mathteacher1729 is that correct?

18. mathteacher1729

@julliemyers Yup, that is correct! :) And your reasoning is very clear as well.

19. julliemyers

What is the inverse of the given relation? y = 3x + 12 =3x=y-12 =x=y/3-4 =y=x/3-4 @mathteacher1729 correct?

20. julliemyers

f(x) = –2x + 4 and g(x) = –6x – 7 f(x) – g(x) (-2x+4) – (-6x –7) -2x+4+6x +7 4x+11

21. mathteacher1729

@julliemyers Yuppers on the inverse problem.

22. julliemyers

f(x) = –2x + 4 and g(x) = –6x – 7 it might be 8x+11 and not 4x+11 >.>
