Question

Anybody want to check my answers for a medal,fan and me loving you forever?!

Answer 1

Given the functions m(x) = 4x − 11 and n(x) = x − 10, solve m[n(x)] and select the correct answer below.
A. m[n(x)] = 4x − 51
B. m[n(x)] = 4x − 29
C. m[n(x)] = 4x^2− 51
D. m[n(x)] = 4x^2 − 29

I got b

Answer 2

Given the functions f(x) = 6x + 11 and g(x) = x + 6, which of the following functions represents f[g(x)] correctly?

f[g(x)] = 6x + 47
f[g(x)] = 6x + 17
f[g(x)] = 6x2 + 47
f[g(x)] = 6x2 + 17
I got A!

Answer 3

\(\large\color{black}{ \displaystyle m[\color{red}{n(x)}] =4(\color{red}{x-10})-11 }\)

first question is NOT b.

Answer 4

Yea i did that and i got 4x-40-11... and -40-11 is -29
so my final answer was: 4x-29

Answer 5

\(\large\color{black}{ \displaystyle f[\color{red}{g(x)}] =6(\color{red}{x+6})+11 }\)

2nd question is done correctly, nice job!

Answer 6

And no, sorry, but the first question is still incorrect

Answer 7

Would it be d then cuz its for sure 29 im just not sure if there is an exponent?

Answer 8

\(\large\color{black}{ \displaystyle m[\color{red}{n(x)}] =4(\color{red}{x-10})-11 }\)
\(\large\color{black}{ \displaystyle m[\color{red}{n(x)}] =4x-40-11 }\)

Answer 9

Let me ask you, what is
40+11=?

Answer 10

51 but isn't it 40-11?

Answer 11

yes, it is -51:)

Answer 12

\(\large\color{black}{ \displaystyle m[\color{red}{n(x)}] =4x-51 }\)

Answer 13

but isn't it 40-11, which is 29?

Answer 14

you said m[n(x)]=4x−40−11... so 40-11 is 29 right? Like why did you add cuz now im confused.

Answer 15

@SolomonZelman

Answer 16

\(\large\color{black}{ \displaystyle m[\color{red}{n(x)}] =4x-40-11 }\)


-40-11 = -51 No?

Answer 17

ohhh I see!! Ok cuz i was just doing 40-11 instead of -40 -11

Answer 18

yeah, that is what you were doing, but now you got it i see(?)

any questuions regarding any of the two problems you posted?
