Question

How do I create a legitimate function

Answer 1

What exactly do you mean?

Answer 2

Like it asks me to create a legitimate function and explain how to use it in complete sentences

Answer 3

I've never heard this term before, but I'm assuming that this function must not break the vertical line test. Then that would not be a valid function

Answer 4

Legitimate function as an explicit function?

Answer 5

idk

Answer 6

You can have any polynomial (( continuous for all values,
on the interval of (-infinity, infinity) ))

y=mx+b
y=mx^2+bx+c
y=mx^3+bx^2+cx+d

and on, ....

((You can make anything up ))

where all those are y functions of x.
and m, b, c, d are any constant.

Or,
y = ln(x)
y = b ln(x)
y = b ln (x + c)
y = b ln (x^m + c)

and etc... (( and again, you can make anything up ))

y = sqrt(x)
(or any other root, with any coefficient.....)

I mean there are nthousands of examples you can think of.

Answer 7

Or, "legitimate" can mean an implicit function as well.

Answer 8

Or, legitimate- as it has to have a slope at least somewhere.
(eliminating vertical lines)

Answer 9

Or just function with some real domain.
Not like y=ln(-x^2)

Answer 10

except that you should use regular numbers, not my abstract m, b, c, d .

Answer 11

good luck, and please reply./.....
