The function f(x) = -x2 - 4x + 5 is shown on the graph. What is the domain and range of this function?

Step 1
The domain includes all the x-values that fall within the function
Hence, the domain of this function is [ All real values of x]
Step 2
Find the range
The range includes all values of y that fall within the function
Hence the range of the function is [-∞, 9]
