Question

I was asked by a teacher to .. "Try to simply calculate 100(f[x+1]/f[x]-1) without plugging in any of x=0 or x=1 to see if it is a function of x."

What does he mean by, "To see if it is a function of x" ?
and "To simply calculate"

Answer 1

Answer 2

and what does he mean by 'simply calculate' ?

Answer 3

was he talking about a particular expression for f(x) ?

Answer 4

oh yeah,., the f[x] = 5.1x^3

Does he just want me to fill in the equation ?

Answer 5

and simplify it?

Answer 6

There is a thing called a function test.

If you can draw a horizontal line anywhere through the graph of a function and if it passes through that function more than once it is not a function

For example:
This is a function a line only can pass through it once


This is not a function a horizontal line can pass through it more than once
