Answer:
Step-by-step explanation:
You first multiply the a with bx and c then after the answer when you multiply you "add" with it would be something like
ex: 6x+4=28
- 4 -4 subtract both sides
------------------------
6x=24 then divide 6 with 24.
x= 3
Answer:
Equation of the parabola:
or 
Vertex form: 
Intercept form: 
Step-by-step explanation: hope this helps please give brainlieat!
Combine like terms
2x^2 + -7x^2 = -5x^2
-9x + 4x = -5x
3 + -2 = 1
put back together
-5x^2 - 5x +1
F(X)= x+1/4x-2
f(2) = (2 + 1)/[(4)(2) - 2]
f(2) = 3/6 = 1/2
True.
Since

,

and the solutions are decreasing functions.
