Answer:
Domain: [-5, 1)
Range: (5, 1]
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the graph, our x-values span from -5 to 1. Since -5 is a closed dot, it is inclusive in the domain. Since -1 is an open dot, it is exclusive in the domain:
[-5, 1)
According to the graph, our x-values span from -5 to 1. Since -5 is an open dot, it is exclusive in the range. Since 1 is a closed dot dot, it is exclusive in the range:
(5, 1]
Personally the easiest way for me is to first find the area of the rectangle and take away the missing triangles. So assuming it’s a rectangle we get (4+5)(3+2) = 45. Ok now we find the area of the triangles. 0.5(4)(3) = 6. Now we subtract that twice from our 45.
45-6-6 = 33. The answer is 33
