M NO ONE IS HELPING Consider the function f(x) = 2x2 +4x – 6.
Over what interval is f(x) negative? Justify your answer.

*ILL GIVE BRAINIEST, FIVE STARS, THANKS*

Step-by-step explanation:

1. Using the limit definition of derivative, find the derivative function,

= −2x + 2.

dont trust my answer dubble check i never trust myself i dont want you to get it wrong

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
