Step-by-step explanation:
To find the gradient:
y2-y1/x2-x1
Pick any two coordinates
11)
(4,3) and (1,-1)
-1-3= -4
1-4= -3
-4/-3 = 1.3(1dp)
12)
(0,1) and ( 2,-2)
-2-1= -3
2-0= 2
-3/2= -1.5
Might be wrong but this is what I got from what I have learnt.
Hope this helps! :)
1. H
2. A
3. E
4. C
I have to type extra words to turn this in so basically I just found the slop of the line then matched it with the letters...
Answer:
The answer to your question is below
Step-by-step explanation:
In blue is f(x) = x² + 3
in red, x =1
F(1) = 1 + 3
= 4
Point = (1,4 ) in yellow
For the answer to this, we turn to the all-important Fundamental Theorem of Algebra<em /><em>, </em>which states that every degree-<em>n</em> polynomial has exactly <em>n </em>imaginary roots. It's important to keep in mind that this theorem doesn't tell you how to <em>find </em>these roots - it just tells you that they <em>exist</em>.
