Let f = 7 x , − 1 y . calculate the work against f required to move an object from (1, 1) to (9, 4) along any path in the first quadrant.

The graph of the function f(x) = (x + 2)(x + 6) is shown below. 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.
