Which statement is true about the graphed function?
F(x) < 0 over the interval (-∞, -4)
F(x) < 0 over the interval (-∞, -3)
F(x) > 0 over the interval (-∞, -3)
O F(x) > 0 over the interval (-∞, -4)

Answer 1

we can see that the function is below the x-axis (negative) for x values less than -4. Therefore, the statement "F(x) < 0 over the interval (-∞, -4)" is true.

However, the function is not below the x-axis for x values less than -3. Therefore, the statement "F(x) < 0 over the interval (-∞, -3)" is false.

Similarly, the function is not above the x-axis for x values less than -3. Therefore, the statement "F(x) > 0 over the interval (-∞, -3)" is false.

Hence, the correct statement is "F(x) < 0 over the interval (-∞, -4)".
