By Graphing the Function, Visually Estimate Its Domain and Range $g ( x ) = x ^ { 2 } - 5$

question 162

Short Answer

By graphing the function, visually estimate its domain and range.
- $g ( x ) = x ^ { 2 } - 5$
A) $\text { Domain: } ( - \infty , \infty ) \text {; range: } ( - \infty , \infty )$
B) $\text { Domain: } [ 5 , \infty ) ; \text { range: } [ 5 , \infty )$
C) $\text { Domain: } ( - \infty , \infty ) \text {; range : } [ - 5 , \infty )$
D) $\text { Domain: } [ 5 , \infty ) ; \text { range: } ( - \infty , \infty )$

• A) \(\text { Domain: } ( - \infty , \infty ) \text {; range: } ( - \infty , \infty )\)
• B) \(\text { Domain: } [ 5 , \infty ) ; \text { range: } [ 5 , \infty )\)
• C) \(\text { Domain: } ( - \infty , \infty ) \text {; range : } [ - 5 , \infty )\)
• D) \(\text { Domain: } [ 5 , \infty ) ; \text { range: } ( - \infty , \infty )\)
