determine all intervals on which f(x) ≥ 0. graph of f answer attempt 1 out of 2 additional solution no solution
Answer
Explanation:
Step1: Identify x - intercepts
The graph of (y = f(x)) intersects the (x) - axis at (x=-9,x = 0,x = 4,x = 8).
Step2: Determine intervals above x - axis
We observe the parts of the graph where (y=f(x)\geq0). The graph is above or on the (x) - axis when (x\in[-9,0]\cup[4,8]).
Answer:
([-9,0]\cup[4,8])
