(-\infty,-2) \cup(2,\infty)

<h2>Explanation:</h2>

Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:

f(x)=x^2-4x

So we need to find the entire interval at which this function positive. Put another way:

f(x)>0

By using graphing tool, we get the graph shown below. As you can see:

  • The function decreases from x=-\infty \ to \ x=0
  • The function increases from x=0 \ to \ x=\infty
  • The graph of the function is a parabola that opens up.

But what is really importan in this problem is that:

  • The function is positive over the interval (-\infty,-2) \cup(2,\infty)

At this interval the function is positive, that is, f(x)>0

This figure is made up of a rectangle and parallelogram.<br> What is the area of this figure?
kondaur [170]

Answer:

51 square units

Step-by-step explanation:

Area of a parallelogram = base x height

⇒ area = 4 x 3 = 12 square units

Area of a rectangle = width x length

width = √(2² + 3²) = √13

length = √(9² + 6²) = √117

area = √13 x √117 = 39 square units

Total area = 12 + 39 = 51 square units
