Find the equation of the quadratic function with zeros -1 and 1 and a vertex at (0,-4)
Stolb23 [73]

The equation is f(x) = 4x^2 - 4.

You can find this by using an equation with parenthesis that equal each of the zeros.

f(x) = (x - 1)(x + 1)

Now, this equation will not give us the vertex that we're looking for. So, we must add a constant being multiplied to the front of it.

f(x) = c(x - 1)(x + 1)

Now we can find the constant by putting our vertex into the equation and solving.

f(x) = c(x - 1)(x + 1)

-4 = c(0 - 1)(0 + 1)

-4 = c(-1)(1)

-4 = -1c

c = 4

Now we put the c into the original equation and solve for standard form.

f(x) = 4(x - 1)(x + 1)

f(x) = 4(x^2 - 1)

f(x) = 4x^2 - 4

Please please please please just answer quickly i have short time left
Nastasia [14]

Answer:

  (x, y) = (10, 4)

Step-by-step explanation:

Opposite sides are the same length, so ...

  ON = LM

  6x -3 = 4x +17

  2x = 20 . . . . . . . . add 3-4x

  x = 10

__

  OL = NM

  x -5 = 3y -7

  10 -5 + 7 = 3y . . . . . substitute x, add 7

  12/3 = y = 4 . . . . . .  simplify, divide by 3

The values of x and y are 10 and 4, respectively.
