anonymous 4 years ago Find the domain and write in interval notation sqrt of (10-2x)

1. anonymous

since you can't square a negative number, you must first solve for x

2. anonymous

10-2x=0, 10=2x, x=5

3. anonymous

$x \epsilon[5,\infty)$

4. anonymous

since $10 - 2x \ge 0$

5. anonymous

6. anonymous
