Answer:
Domain: {9, 8, 7,-5} Range: {1,-3, 5, 3}
Step-by-step explanation:
The domain is the input values or the x values
The range is the output values
This is a functions since no inputs go to more than one output
D = {-5, 7, 8, 9}
R = {-3, 1, 3, 5}
Since 'C' does not repeat any domain values, it is a function.
The x-values of a function are the domain.
{(9, 1) (8,-3) (7,5) (-5,3)}
The domain is {-5, 7, 8, 9}.
The y-values of a function is the range.
The range is {-3, 1, 3, 5}.
144km^3
2x(squared)-8x
when you distribute the 2x to x you get 2x squared and when 2x is distributed to -4 you get -8x and together you get 2x squared minus 8. :)
should be:
x^3 + 27
hope it helps
