Write the equation of the parabola in vertex form.
vertex (2,1), point (3,- 1)
f(x) =

Step-by-step explanation:

Given the vertex, (2, 1) and point (3, -1):

We can plug in those values into the Vertex Form:

Plug in the other point, (3, -1) into the equation to solve for a:

-1 = a1 + 1

Subtract 1 from both sides of the equation to solve for a:

-1 - 1 = 1a + 1 - 1

-2 = 1a

-2 = a

Therefore, the equation of the parabola in Vertex Form is:

where a = -2, and the vertex, (2, 1) as its maximum point.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
