Answer:
C
Step-by-step explanation:
The range is the set of y values for the function
The graph in C lies entirely above and equal to -6.
The graph is shown in option C) shows the values of 'y' greater than or equal to -6. Therefore, the correct option is C).
The following steps can be used to determine the graph that represents a function with a range of all real numbers greater than or equal to -6:
Step 1 - Observe all the graphs given in the option. It can be easily concluded that all the four graphs show parabola.
Step 2 - Now, again observe all four graphs and try to find which graph shows the value of 'y' less than -6.
Step 3 - So, by observing it can be found that graphs B) and D) show the value of 'y' less than -6. Therefore, these options are not correct.
Step 4 - Now, there are two graph A) and C) that shows the value of 'y' greater than -6.
Step 5 - It can be clearly seen that graph A) only shows that values of 'y' greater than or equal to zero. Therefore, this graph is also incorrect.
Step 6 - The graph is shown in option C) shows the values of 'y' greater than or equal to -6. Therefore, the correct option is C).
