Look at the y axis. You can see that the graph reaches a minimum at y=3, and then grows indefinitely.
This implies that the range is . In fact, the range is exactly the set of all values reached by the function's outputs.
The vertical line test states that a graph is a function if and only if every possible vertical line crosses the graph at most once.
You can see that this is the case, so this is the graph of a function indeed.
The correct answer is D) y + 1 = 4/3(x - 9)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form.
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 1 = 4/3(x - 9)
Answer:
560880
Step-by-step explanation:
AGAIN
We know that -1/4x means we have a negative slope, which excludes the 1st graph from our answer choices.
Second, we know that the y-intercept has to be 3, excluding the second and third graph.
This leaves us with the 4th graph as our answer
