Answer:
a2
Step-by-step explanation:
The range is virtually the answer to the question,
"In which interval can find all y-values of the function".
So you look at the y-axis and see that your function begins with (including -5 because of the dot on the graph) and ends at including .
So the interval notation is,
But you are asked to specify the set notation of the interval, to do so first rewrite the interval using inequality operators, say we find some y in between (and including) -5 and -1,
To specify that this is a set use curly bracelets and a bar,
.
The y before bar is a step function and everything followed after the vertical bar is the range of the step function.
Hope this helps.
Answer:
y = 1/2x
Step-by-step explanation:
Substitute the given information into the equation y = mx + b
<em>Your goal is to find what b is</em>
Obviously, the point given --> (4, 2) is the x and y.
The m is the slope (1/2)
