Question

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

Answer 1

(c) m[n(x)]=\[4x^2-51\]
(d) m[n(x)]= \[4x^2-29\]

Answer 2

\[\large\textrm {m[n(x)] is same as m(x-10)} \]

Answer 3

substitute x for n(x) function which is x-10 into m(x) function

Answer 4

...what??

Answer 5

:P

Answer 6

n(x) =x-10
so they want u to replace x for x-10 into m(x) function
so\[\huge\rm m(\color{Red}{x-10})=4\color{reD}{x}-11\]
replace x with x-10

Answer 7

make sense ?

Answer 8

sorta..? ugh im so confused..now what?

Answer 9

so now its 4 (x-10) - 11 ?

Answer 10

its 4x-29! i get it now! lol, big help, thanks!

Answer 11

how??

Answer 12

distribute parentheses by 4
4(x-10))=? ??
distribute parentheses by 4

Answer 13

4(x-10)-11 = 4x- 40- 11 = 4x - 29

Answer 14

-40-11= ?

Answer 15

both are negative so you would add

Answer 16

oh..so then its 4x-51?

Answer 17

yes right

Answer 18

u rock..thank you!

Answer 19
