Answer:
y = -3
Step-by-step explanation:
y = x - 7
when x = 4
y = 4 - 7
y = -3
The domain of a function is the set of all values x can have.
From the graph, we see the least value of x is 3. x can be any value greater than or equal to 3.
The domain is
8,000,000 + 200,000 + 5,000
X=15/7 (in exact form) or x= 2 1/7 (in mixed number form) or x= 2.142857 (in decimal form)
It could be
5 + 4 = 3 squared, or
5 + 4 = 3 x3
