Parabolas
Fichas del conjunto (24)
- 1Focus of a parabolaThe point inside the parabola that is p units away from the vertex
- 2Directrix of a parabolaThe line outside the parabola that is p units away from the vertex
- 3State the critical point of the following parabola(1,6)
- 4Will the graph have a maximum or minimum? Why? What is the value of it?Maximum because the graph is facing downwards and it will equal 6.
- 5State the transformationsvertical stretch by factor of 4
right 6 units
up 4 units
- 6What are the rules for adding and subtracting fractions?Must have a common denominator and then you only add the numerators.
- 7State the definition of a chord of a parabola. How does it help you graph the parabola?The chord of a parabola is a line through the focus that is 4p units long.
It helps you graph by allowing you to plot two other points on the parabola. - 8What is the critical point?(6, 1)
- 9State one thing different and one thing the same about the FOCUS and DIRECTRIX of a parabola.Differences:
One is a point and one is a line.
One is inside the parabola and one is outside the parabola.
Same:
Neither touch the parabola
They are both p units away from the vertex/critical point - 10Which direction will the graph open? Why?Left because the equation starts off as x = and a is negative.
- 11Do parabolas have slope? If yes, why. If no, why not and what would you label that value as?No because parabolas are curved and not a straight line. We refer to that value as the a value.
- 12In the formula, will a be a vertical or horizontal transformation? Why?Vertical transformation because it is outside the grouping symbols.
- 13Vertical transformation because it is outside the grouping symbolsIf a > 1 then you have a vertical stretch.
If a < 1 but positive, you have a vertical compression. - 14What is the domain of all parabolas?All real numbers
- 15How do you find the y-intercept of any equation without creating a graph?Plug in 0 for x.
- 16What are the rules for multiplying fractions?Multiply the numerators and multiply the denominators straight across.
- 17How do you find the x-intercept of any equation without creating a graph?Plug in 0 for y.
- 18What's a zero? How do write it as a coordinate?x - intercept
(#, 0) - 19When can we cross multiply fractions?When you have one fraction equal to another fraction.
- 20How do you calculate the p-value of a parabola?
- 21Which will produce a graph skinnier than the quadratic parent function? Why?A. will produce a skinnier graph because
a > 1 and the graph vertically stretches.
- 22What's the zero of the given function?(4,0)
- 23What's the y-intercept of the given function?(0, 6)
- 24State the vertex of the equation. Will the graph have a minimum or maximum at the vertex? Why?(-7, -k)
Minimum because a is positive which means the graph is opening up.
