Which ordered pairs represent points on the graph of f(x)= Negative RootIndex 3 StartRoot x EndRoot? Check all that apply.
DedPeter [7]

Answer:

  • (0, 0)
  • (1, –1)
  • (8, –2)

Step-by-step explanation:

We normally think of the ordered pairs as ...

  (x, y) = (x, -∛x)

Another way to think about them is ...

  (x, y) = (-y³, y)

I find it a little easier to think about the cube of a number, rather than its cube root.

For the y-values given, -2, -1, 0, 2, the points that will be on the graph are ...

  (8, -2), (1, -1), (0, 0), (-8, 2)

The first three of these points are listed in your answer choices.

what is the general form of the equation of a circle with its Center at -2 1 and passing through -4 one
nydimaria [60]

Answer:

x² + y² + 4x - 2y + 1 = 0

Step-by-step explanation:

The equation of a circle is given by the general equation;

(x-a)² + (y-b)² = r² ; where (a,b) is the center of the circle and r is the radius.

In this case; the center is (-2,1)

We can get radius using the formula for magnitude; √((x2-x1)² + (y2-y1)²)

Radius = √((-4- (-2))² + (1-1)²)

             = 2

Therefore;

The equation of the circle will be;

(x+2)² + (y-1)² = 2²

(x+2)² + (y-1)² = 4

Expanding the equation;

x² + 4x + 4 + y² -2y + 1 = 4 subtracting 4 from both sides;

x² + 4x + y² - 2y + 4 + 1 -4 = 0

= x² + y² + 4x - 2y + 1 = 0
