(a variation of) vertex form
For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...
y = a(x -h)^2 +k
If k is subtracted from this equation, an alternate form is ...
y -k = a(x -h)^2
This latter version of vertex form is the form your equation has, where ...a = 8(h, k) = (-7, -20)
y= - 2(x - 3)(x+5) is Factored form
Step-by-step explanation: Quadratic equation forms
Vertex form is y = a(x -h)² + k
Standard form is y = ax² + bx + c
Factored form is
As the other person stated, the answer is standard. I hope we helped :
Cartesian Form ⇒ completing square
y - 3 = 1/2(x - 1)²
y = 1/2(x - 1)² + 3 ⇒ vertex (1 , 3) minimum
I believe it is standard form?
It's a point-slope form of a line:
m - slope
(x₁, y₁) - the point the line passes through
We have y + 20 = 8(x + 7)
slope m = 8
point : (-7, -20)
we know that
A quadratic function written in standard form is
in this problem we have
The given equation is in vertex form.
We have given a quadratic equation.
y-3 = 1/2(x-1)²
We have to find the form of the function.
y-k = a(x-h)² is vertex form of equation in which (h,k) is vertex of equation.
Comparing vertex form and given equation, we have
k = 3 and h = 1
Hence, vertex is (1,3).
So, the given equation is in vertex form.
There are 3 different forms of functions:Standard Form [ f(x) = ax² + bx + c ]Intercept Form [ f(x) = a(x - p)(x - q) ]Vertex Form [ f(x) = a(x - h)² + k ]
y + 2 = -(x + 4)² is an example of vertex form of a parabola [ (h, k) is the vertex ]
The vertex of the function is (-2, -4)
Therefore, the answer is Vertex Form.
Best of Luck!
It is parabolic equation.
Vertex form of parabola:
where, (h,k) is vertex of parabola.
The given equation similar to vertex form of parabola.
The vertex of equation is (-4,-2)
Hence, The function written in vertex form.
