Answer:
Discriminant = 20
Step-by-step explanation:
We use formula to find the discriminant.
Discriminant (D) = b^2 - 4ac
The given equation is x^2 - 6x + 4 = 0.
Here the value of a = 1, b = -6 and c = 4.
Plug in the given values in the formula, we get
Discriminant (D) = (-6)^2 - 4*1*4
= 36 - 16
Discriminant = 20
Thank you.
There can be no negative in a sqrt
so x+1 must be equal or greater then 0
x+1
0
x
-1
so all answers must be greater then or equal to -1
-1,0,1,2,3,4,5,6,7,8
(-1,infinity) is the domain
Since the lines are parallel and you know the slope of
is -2, you know the slope of line
will also be -2. You can see on the coordinate grid that line
crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get
= -2x - 1.
