Possible Answer:

1. I understand that when graphed, a quadratic function has the shape of a parabola.

2. I have a question about the quadratic function when graphed. The lines can point up or down, but why can't the function go left or right?

Step-by-step explanation:

These are just possible answers, everyone else can have different things, especially the second question.

These should be your answers though. I’ll help but still.

1.) I understand that quadratic functions are in the form of y = ax^2 + bx + c and that when placed on a graph, it will show a parabola.

2.) I have a question about how to get the vertex of a parabola and it’s vertex form.

Hope this is plausible enough.

Write the equation in standard form for the circle that has a diameter with endpoints (6, -9)

nevsk [136]

Answer:

Step-by-step explanation:

By definition a diameter goes through the center of the circle. So if we find the midpoint of the diameter, we will have the h and k of the center. Then we will use one of the points ON the circle as x and y and solve for r. Here goes:

$M=(\frac{6+(-6)}{2},\frac{-9+(-9)}{2})$ to get a midpoint/center of (0, -9).

The standard form of a circle is

$(x-h)^2+(y-k)^2=r^2$

Filling in with h, k, x, and y:

$(6-0)^2+(-9-(-9))^2=r^2$ which simplifies to

$6^2+0^2=r^2$ so

$r^2=36$

Now we can write the equation of the circle:

$x^2+(y+9)^2=36$

SOME ONEEE PLZZ HELPP MEEEE

Dominik [7]

Answer:

2.5

Step-by-step explanation:

The minimum value is the minimum y-value a function includes. In this case, since you can see the function is periodic (it repeats itself <em>periodically</em>, hence periodic) and the smallest y-value the function encounters is 2.5 (doesn't go below this value), the minimum y-value is 2.5. I hope this made sense. If not, feel free to let me know.
