Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
The domain is all of the x values in a set and the range is all of the y-values in a set.
If you have a bunch of points such as (3,6), (7,2), (1,5) the domain would be stated as D={3, 7, 1} and the range would be stated as R={6,2,5} If you have a line, then the domain and range would be set up differently. For example, if you have a line with end points at (-3,2) and (5,8) then the domain would be D=(-3,5) and the range would be R=(2,8)

Answer: y= -2/5x + 2
Step-by-step explanation:
Y= Mx + b
M is the slope
B is the y intercept
The y intercept will be out on the y axis
The slope will be rise over run ( do you first then do to the right!)
The vertical asymptote is r = 0.
The intensity is undefined at the source.
The horizontal asymptote is I = 0.
As the distance from the source increases, the intensity goes to zero.
The intensity decreases as the distance increases.
