Question

How do you evaluate the function `f(x) =x^2- 7x + 10` and `g(x)=1-x^2` for f(0)?

Answer 1

See a solution process below:

Explanation:

Because we are evaluating `f(0)` the function `g(x)` plays no role in this question.

Substitute `color(red)(0)` for each occurrence of `color(red)(x)` in the function `f(x)`:

`f(color(red)(x)) = color(red)(x)^2 - 7color(red)(x) + 10` becomes:

`f(color(red)(0)) = color(red)(0)^2 - (7 * color(red)(0)) + 10`

`f(color(red)(0)) = 0 - 0 + 10`

`f(color(red)(0)) = 10`
