The equation of the parabola is y = a(x - h)^2 + k, where (h,k) is the coordinates of the vertex. In this case, the equation would be y = 4(x + 9)^2 + 2.
Any point on a parabola is equally distant from the directrix, a fixed straight line, and the focus, a fixed point. An U-shaped plane curve is a parabola.
Drawing a parabola for the quadratic function f(x) = + bx + c results in a U-shaped curve. When an is smaller than zero, the parabola's graph is downward (or opens downward). When the value of an is greater than 0, the parabola's graph ascends (or opens up).
Every point on a parabola is equally distant from both a focus, or central point, and a directrix, or connecting line. It is a U-shaped curve that frequently appears in math.
Given,
Graph f(x) =
Vertex = (-9,2) = (h,k)
So, We can represent the equation in the form of
f(x) = y = a + k
= 4 + 2
Now simplifying the equation y = a + k to y = + bx +c
f(x) = 4 + 2
= + 72x + 326
∴ f(x) = + 72x + 326 is the equation of parabola

Answer:
The temperature was higher on Wednesday than on Tuesday.
Step-by-step explanation:
-5<5
Well, yes and no.
Yes, because the straight line needs to pass through a number greater than 0, and 1 is obviously greater than 0.
However, y = x + 1 is not the same as y = x.
hope this helps.! let me know if it's in any way confusing..
I'd be happy to help!
