#13.%0D%0A %0D%0AThe graph of a quadratic function fis shown on the grid. Which of these best represents the domain of f?%0D%0A%0D%0A%0D%0A−4≤x≤5%0D%0A%0D%0Ay≥−12.25%0D%0A%0D%0AAll real numbers %0D%0A%0D%0AAll real numbers less than -4 or greater than 5
The correct representation of the domain of the quadratic function is:
-4 ≤ x ≤ 5
This is because the graph of the quadratic function is bounded by x values between -4 and 5. Therefore, the domain of the function f is -4 ≤ x ≤ 5.
Are you sure?
Apologies for the oversight. Let's take another look at the options provided:
-4 ≤ x ≤ 5: This represents the x-values within the bounds shown on the graph.
y ≥ -12.25: This does not specifically address the x-values or domain of the function, but instead suggests a lower boundary for the y-values.
All real numbers: This would include all possible x-values, but could be too broad for the specific graph shown.
All real numbers less than -4 or greater than 5: This would include x-values outside the bounds of the graph shown.
Based on the graph of the quadratic function shown and the options provided, the most appropriate representation for the domain of the function would be:
-4 ≤ x ≤ 5
This represents the x-values within the constraints of the graph.
