Problem 165 of 7
State domain restrictions before solving modeled equation log(x+4)=2.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
identify denominators, radicands, logs, and context limits.
Hidden until you reveal it.
Identify denominator, radicand, logarithm, and context restrictions before solving.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Inspect denominators, radicals, logs, and context quantities.
2. Write restrictions as equations or inequalities.
3. Use them to filter later solutions.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Solving first and only checking some restrictions afterward.
