Question

how do i find the inverse of
C(n) = 28n+5700

Answer 1

make n in the subject of the function
replace C(n) by n
and n by C(-1) n

Answer 2

n = 28(c(-1)) + 5700

Answer 3

you've done the replacement before making n the subject
making n the subject means rearranging the formula to get n =

Answer 4

C(n) = 28n+5700
28n = C(n) - 5700
can you continue?

Answer 5

ah. divide both sides by 28 . and ill have my inverse?

Answer 6

then you'll have n = whatever
then you do the replacements

Answer 7

i think i understand... but just to be clear.. am i just replacing n with C^-1(n)

Answer 8

thats part of it - also replace C(n) on the righthand side by n

Answer 9

ok. thank you so much
