Answer:
D: [8, 12].
R: [-10, -6].
Step-by-step explanation:
Notice that the endpoints of the graph are closed circles. This means that square brackets will be used:
The graphed equation is from x = 8 to x = 12. Therefore, the domain of the function is:
D: [8, 12].
The range goes from y = -10 to -6. Therefore:
R: [-10, -6].
Answer:
-16
Step-by-step explanation:
Let's call the number x. Double the sum of x and seven is 2(x + 7) and two less than x is x - 2. Since these are equal we can write:
2(x + 7) = x - 2
2x + 14 = x - 2
x = -16
