A which is 4 i think is the right answer
The answer to this is 1 pound and 4 ounces.
Answer:
-9 ≤ x < 2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values span from -9 to 2. Since -9 is closed dot, we include it in our domain. Since -2 is open dot, it is excluded from our domain:
[-9, 2) or -9 ≤ x < 2
In point slope form we are told the equation is y - 8 = (x - 4). To represent it as a function, we solve both sides for y, since y is written as a function of x, f(x).
y - 8 = (x - 4)
y - 8 = x - 4 parentheses are taken away since there's nothing outside
y = x + 4 add 8 to both sides
f(x) = x + 4 to rewrite with y = f(x).
Thus, the function f(x) = x+ 4 (first one) is the right representation.
