<u>Part 1: Finding </u>
Note that 
In this case, it is 
<u>Part 2: Domain</u>
For the domain, we need to make sure the radicand of h(x) is greater than or equal to 0, so we get 
Answer:x=2.6
Step-by-step explanation:
Simplifying (5x + 15) = 28 Reorder the terms: (15 + 5x) = 28 Remove parenthesis around (15 + 5x) 15 + 5x = 28 Solving 15 + 5x = 28 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + 5x = 28 + -15 Combine like terms: 15 + -15 = 0 0 + 5x = 28 + -15 5x = 28 + -15 Combine like terms: 28 + -15 = 13 5x = 13 Divide each side by '5'. x = 2.6 Simplifying x = 2.6
