Question

If `f(x) = x(2x-1)`, what is `f(0)`?

Answer 1

See a solution process below:

Explanation:

To find `f(0)` substitute `color(red)(0)` for every occurrence of `color(red)(x)` in `f(x)`:

`f(color(red)(x)) = color(red)(x)(2color(red)(x) - 1)` becomes:

`f(color(red)(0)) = color(red)(0)((2 xx color(red)(0)) - 1)`

`f(color(red)(0)) = color(red)(0)(0 - 1)`

`f(color(red)(0)) = color(red)(0) xx -1`

`f(color(red)(0)) = 0`
