Answer:
Column 1 is labeled x with entries negative 3, negative 2, 4, 7. Column 2 is labeled y with entries negative 1, 5, 0, negative 1
Step-by-step explanation:
When a value is repeated for an x-entry, the relation is not a function. The last choice describes a table with unique x values.
Answer:
12 and 13
Step-by-step explanation:
(a)
To evaluate f(g(2)), evaluate g(2) then use the value obtained to evaluate f(x)
g(2) = 2(2) - 1 = 4 - 1 = 3, then
f(3) = 3² + 3 = 9 + 3 = 12
--------------------------------------------
(b)
To evaluate g(f(2)), evaluate f(2) the use the value obtained to evaluate g(x)
f(2) = 2² + 3 = 4 + 3 = 7, then
g(7) = 2(7) - 1 = 14 - 1 = 13
Answer:
On Graph B, at 0 hours, the graph will be at 0 feet.
Then, the graph will increase until 1 hour, when the submarine reaches its deepest point.
At 1 hour, the height of Graph B will be 4000 feet.
