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

See a solution process below:

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

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

$f (x) = x^{2} - 7 x + 10$ $f(color(red)(x)) = color(red)(x)^2 - 7color(red)(x) + 10$ becomes:

$f (0) = 0^{2} - (7 \cdot 0) + 10$ $f(color(red)(0)) = color(red)(0)^2 - (7 * color(red)(0)) + 10$

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

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