can anyone remind me on how to get the domain and range from points like the one below:
{(-5,7), (0,0), (2,-8), (-7,7)}
thanks.
domain-
-7<x<2
range-
-8<y<7
how did you get the answer? is it the smallest value and greatest value of y and x?
cause -7 is the smallest for x
2 is the greatest for x
-
and -8 is the smallest for y
7 is the greatest for x
not sure about this though.
To find the domain and range from a set of points, such as the ones you provided: {(-5,7), (0,0), (2,-8), (-7,7)}, follow these steps:
1. Domain: The domain refers to the set of x-values (the values along the horizontal axis). To determine the domain, find the unique x-values from the given points. In this case, the x-values are -5, 0, 2, and -7. So, the domain is {-5, 0, 2, -7}.
2. Range: The range represents the set of y-values (the values along the vertical axis). To determine the range, find the unique y-values from the given points. In this case, the y-values are 7, 0, and -8. So, the range is {7, 0, -8}.
Therefore, the domain is {-5, 0, 2, -7} and the range is {7, 0, -8} for the given set of points.
