Answer:
Step-by-step explanation:
1. f(x) < 0
Interval of the domain where the graph is below the x-axis
because the negative regions of a function compromises those intervals where the function lies below the x-axis
2. x-intercept
Location on graph where output is zero
because when we find x-intercept we put y=0
3. y-intercept
Location on graph where input is zero
because when we find y-intercept we put x=0
4. f(x) > 0
Interval of the domain where the graph is above the x-axis
because the positive regions of a function compromises those intervals where the function lies above the x-axis
