Hello from MrBillDoesMath!
Answer:
The second choice
Discussion:
The first choice is not a polynomial because it contains sqrt(x)
The third choice is not a polynomial because it contains (1/x)
The fourth choice is not a polynomial because it contains x in the exponent (ie. 5^x)
Thank you,
MrB
The equation of line perpendicular to given line is:

Step-by-step explanation:
Given equation is:

First of all, we have to find the slope of the given line
So,

Dividing both sides by 2

As the equation is in slope-intercept form, the co-efficient of x will be the slope of the line

As we know that product of slopes of two perpendicular lines is -1
Let m-2 be the slope of line perpendicular to given line

Slope-intercept form is:

putting the value of the slope

Putting the point (3,1) in the equation

Putting the value of b

Hence,
The equation of line perpendicular to given line is:

Keywords: Slope-intercept form, slope

Answer:
False
Step-by-step explanation:
This graph is not a function because it fails the vertical line test where you draw a vertical line through the graph and if the vertical line touches the graph more than once it fails the vertical line test which means it is not a function.
Hope this helps!
