Step-by-step explanation:
you juts add them all together
Answer:
Below in bold.
Step-by-step explanation:
x^2 - 2x - 3 = 0
(x - 3)(x + 1) = 0
The zeroes are -1, 3.
Change to vertex form:
= (x - 1)^2 - 1 - 3
= (x - 1)^2 - 4
So the axis of symmetry is x = 1.
The vertex is at (1, -4) and it is a minimum (because the coefficient of x^2 is positive).
Domain is (-∞, ∞)
Range is [-4, ∞).
Increasing when x < 1.
Decreasing when x > 1.
End behaviour x ---- -∞ , y --> ∞
x ----> ∞, y ---> ∞
Answer:
don't you substitute the the x to find y
Answer:
5
Step-by-step explanation:
You do 12 x 3 which is 36.
you then do 1/3 x 3 which is 1.
36-1 is 35.
you then do 4x3 which is 12.
you then do 12-5 which is 7.
you then do 35÷7=5
this is why it is 5.
