How do you to tell the difference between an ellipse, hyperbola, parabola, or circle if all are in standard form?

NeX [460]

Step-by-step explanation:

General form of a conic section is:

Ax² + Bxy + Cy² + Dx + Ey + F = 0

If B = 0:

Parabola: Either x² or y² term, but not both

Circle: x² and y² have the same coefficient

Ellipse: x² and y² have different positive coefficients

Hyperbola: x² and y² have different signs

Otherwise, look at the discriminant.

If B² − 4AC < 0, then the conic is an ellipse.

If B² − 4AC = 0, then the conic is a parabola.

If B² − 4AC > 0, then the conic is a hyperbola.

Shift y=5x 3 units up

77julia77 [94]

y = 5 x +3 is the final equation when y = 5 x 3 units up

<u>Step-by-step explanation:</u>

In mathematics, a function is a relation between sets that associates to every element of a first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

Here we have , y=5x . Function y = 5x is a straight line passing through origin and having a slope of 5 . Now we need to increment this function 3 units up i.e. y = 5x + 3 , This a straight line passing through x-axis at $\frac{-3}{5}$ and y-axis at 3. For your reference , following graph of y= 5x and y = 5x + 3 is attached .
