Explanation of Solution
Given information:
An expression is given as -
Concept used:
Domain of an expression is set of all real values of
Calculation:
Given expression is -
This function is defined only if
So, domain of the expression is given by −
Key numbers are
Test interval | Test | Expression value | Conclusion |
Negative | |||
Positive | |||
Negative | |||
Positive |
From above table, it can be concluded that inequality
Therefore, solution set for the given inequality will be
Graph of the solution set is drawn below.
Hence, domain of the given expression will be

Precalculus with Limits
- Consider the graphs of y = f(x) and y = g(x) in the given diagram y= f(x). y = g(x) Evaluate (f+g)(2) -5 Determine all for which g(x) < f(x) Determine all for which f(x) +3 = g(x)arrow_forwardI) For what value(s) of x does g(x) = -4? Separate multiple answers with commas as needed. J) Give the interval(s) of such that g(x) > 0. Use the union symbol between multiple intervals. K) Give the interval(s) of such that g(x) <0. Use the union symbol between multiple intervals.arrow_forwardneed help on Barrow_forward
- 4. Use the properties of limits to help decide whether each limit exists. If a limit exists, fi lim (2x²-4x+5) a) x-4 b) lim 2 x²-16 x-4x+2x-8arrow_forward7. The concentration of a drug in a patient's bloodstream h hours after it was injected is given by 0.17 h Ah= h²+2' Find and interpret lim A(h). Remember, the answers to word problems should always be given in a complete h→00 sentence, with proper units, in the context of the problem.arrow_forward#2arrow_forward
