Answer in picture below
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: C
<u>Step-by-step explanation:</u>
Let x represent the first term (a₁)
a₁ = x
a₂ = x(-√2) = -x√2
a₃ = -x√2(-√2) = 2x
a₄ = 2x(-√2) = -2x√2
a₅ = -2x√2(-√2) = 4x
Since it is given the a₅ = √2, then we can solve: 4x =√2
Divide both sides by 4 to get: x =
this can also be written as:
