Question

whats the difference between explicit functions and linear functions?

Answer 1

An explicit function is a function of the form y = f(x).
A linear function is a function of the form y = ax + b.

Answer 2

then why isn't a linear function explicit?

Answer 3

y=2x+1 is an explicit function,but it also looks like a linear function,how do i differ?

Answer 4

i have no real idea what this question is asking, but
\[y=2x+1\] is not a function, it is an equation

Answer 5

A linear function written as y = ax + b is an explicit function.

Answer 6

ok,thankyou emarald000.i got it!

Answer 7

you can certainly make it into a function by saying
\[f:=\{(x,y)|y=2x+1\}\] for example or even
Let
\[f(x)=2x+1\]

Answer 8

@satellite: That is what i meant,you gave it a better representation though.
