Answer 1

Answer:

a funsion is negative on intervals where the graph line lies below x axis

Explanation:

example : that's bcz the value of these points are zero ( zero is neither +'ve nor -'ve

Answer 2

We can also reflect the graph of a function over the x-axis (y = 0), the y-axis(x = 0), or the line y = x. Making the output negative reflects the graph over the x-axis, or the line y = 0. Here are the graphs of y = f (x) and y = - f (x).

Explanation:

A function is negative on intervals (read the intervals on the x-axis), where the graph line lies below the x-axis. Example: The parts above the x-axis (positive values): The part below the x-axis (negative values):
