Question

Which statement about the function is true? The function is positive for all real values of x where x>-4, . The function is negative for all real values of x where - 6 < x < - 2 . The function is positive for all real values of x where x < - 6 or x > - 3 . The function is negative for all real values of x where x < - 2

Answer 1

Answer:

B. The function is negative for all real values of x where

–6 < x < –2.

Step-by-step explanation:

Just took the test

Answer 2

The Function f(x) is positive for the values x ≤ -6 and x ≥ -2 and negative in the interval -6 ≤ x ≤ -2 is true.

Definition of real number:

We generally utilize numbers like 1, 15.82, 0.1, 3/4, and so on.

Real Numbers can be positive or negative, huge or tiny, whole values, fractions, or decimal numbers.

Because they are not Imaginary Numbers, they are referred to as "Real Numbers."

Step by step:

Given function is a quadratic function, as seen in the graph,

f(x) = (x + 2)(x + 6)

x = -6 and -2 are the function's x-intercepts.

The negative values of the function are shown by the graph below the x-axis.

The positive values of the function are represented by the graph above the x-axis.

Hence, the function f(x) is positive for the values x -6 and x -2, but negative for the interval -6 x -2.
