Answer:
Domain: {4,5,7,10}
Range: {2,4,8}
Not a function
Step-by-step explanation:
The domain is all the x-values.
The range is all the y-values.
However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

Answer:
6
Step-by-step explanation:
m = 3
n = 1
Equation
m(m - n) Substitute the givens
Solution
3(3 -1 ) Evaluate what is inside the brackets.
3(2) multiply
6
(r + 10)(r - 4)
To double check:
r * r is r^2
10 * r = 10r; -4 * r = -4r
Combine to get 6r.
-4 * 10 = -40
