Question

Evaluate the function f(x)=10-x for the domain {-2, 0, 2}

Answer 1

For this case we have a function of the form $y = f (x)$, where:

$f (x) = 10-x$

We must find the value of the function when:

$x = -2,0,2$

• For $x = -2:$

$f (-2) = 10 - (- 2) = 10 + 2 = 12$

• For $x = 0$:

$f (0) = 10-0 = 10$

• For $x = 2$:

$f (2) = 10-2 = 8$

Thus, we have that the function has a value of $y = {12,10,8}$ when $x = {- 2,0,2}$

Answer:

$y = {12,10,8}$
