Which statements describe the graph of y = 3x - 1+2? Select three options.
2 answers:
Answer:
<h2>The graph has a domain of all real numbers.</h2><h2>The graph has a y-intercept at (0, 1).</h2>Step-by-step explanation:
The given function is
This is linear function, the domain and range of linear functions are always all real numbers, because they don't have any kind of restriction. So, the first option is right.
In addition, linear function are represented by a line which has interceptions with each axis. The interceptions with the vertical axis is when :
So, the fourth option is right,
Similarly, the interception with the horizontal axis is when :
This means the last option is not correct.
Therefore, all options that apply are
- The graph has a domain of all real numbers.
- The graph has a y-intercept at (0, 1).

Answer:
The graph in the attached figure
see the explanation
Step-by-step explanation:
we have
we know that
The radicand must be greater than or equal to zero
so
solve for x
Adds 3 both sides
Multiply by -1 both sides
Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The domain of the function is the interval (-∞,-3]
For x=-3 ---> the value of y=0
The range is the interval {0,∞)
therefore
The graph in the attached figure
