• I need help for Math! (Lambacher Swiss 8 S.200 No.3)12-24

Heyyy, I'm learning for ne math test and not get ahead ... :( The question is P "The point P lies on the parabola Determine to this, the corresponding function equation." (1 | 3) was my idea, with y .. = 3 to start, because the slope is yes 3 an

• How the coordinate of the vertex determined in these examples?11-07

y = x ^ 2 - 6x + 5 Or y = x ^ 2 + 5x + 6.75 Please help me! --answer-- Hello, with such functions You choose the vertex in the simplest way that you can in front of the x changes sign at the number - from -6 is therefore 6, and then sharing before x²

I had in the last question too little information. So I have two points and need the normal parabola. Q (-2/1) S (3 / -4) Is an open upward normal parabola. Normal parabola: y = x ^ 2 maybe somehow the apex shape out Ps? --answer-- You have to point

• Hilfeeeee! We write soon ne math work about parables / quadratic functions!04-27

So we had some months ago this issue and I have really understood very well but it's been a while and now I'm writing a math work about it and I understand nothing more º º □ the someone please tell me can? Ex .: f (x) = 1 / 2x high 2 how do I calcul

• Are parabolic trough and Parabspiegel the same?03-09

--answer-- No: Parabolic troughs are mirror symmetrical to a plane and focus the light onto a line. Parabolic mirrors are rotationally symmetric to an axis and focus the light to a point. Parabolic troughs are parabolic cylinder. Parabolic mirror can

• I write tomorrow a class work and have just come across two issues where I need help. Can someone help me?03-06

--answer-- At task 18: a) intersections again calculate the equating process: pq-formula and then use x-values ​​in the original equations to get the y-values ​​(must be the same for both). b) Well, here's the strange ... If we start with g thereof,

• how can I check whether a given point lies on a parabola?09-10

A parable of the form f (x) passes through the point P = ax² (-1 / -0.25). a) Determine the function equation .b) Check whether the point Q (2 / 0.5) is on the parabola found. I for hours been sitting on all forms, but can not get out there, it's too

• If the function term that same as the functional equation?09-04

Or are there differences and if so, what? --answer-- An equation always has an equal sign, a term is quasi one side of the equal sign. If you are for example as f (x) = 2x is the function equation, the function expression 2x A function term is what f

• Can you draw a parabola without the equation to bring in the vertex form?12-25

for example, if x ^ 2 is negative, so -x ^ 2 --answer-- The indicated from you parabola can be easily drawn. Minus ahead is: open downward. Only x² means normal parabola (for you probably a template) Only one number after x² is, at this point is the
