Key Features of Function (Part 2) | Algebra
Просмотров 9710 месяцев назад
In Part 2, I explain the key features of function, domain and range, max and min, increasing and decreasing interval. After watching Part 1 and Part 2, you should have a basic idea about function. In the end, I give a brief introduction to all different types of functions that you learn in high school Math.
What is a Function Exactly? (Part 1) - Algebra
Просмотров 23010 месяцев назад
In this video, I explain what a function is in simple words. Knowing the definition of function is critical in learning Algebra. I also explain the difference between function and equation, how to verify if a graph is a function, and 4 different ways to represent a function. In Part 2, I'll go over more details about a function, such as domain, range, increasing/decreasing, x and y intercepts, ...

    • @mr.snuffulmuffin6954
      @mr.snuffulmuffin6954 2 месяца назад

      This context is a acid-base reaction, so the proton from HF (H+) is donated to the OH molecule. This results in H2O being formed and a spectator molecule that results from the leftover atoms (Na and F -> NaF).

    • @mr.snuffulmuffin6954
      @mr.snuffulmuffin6954 2 месяца назад

      It should be noted however, that she got it wrong in this case because HF is a weak acid and does not dissociate and therefore HF should stay together in the final reaction, netting HF + OH- --> F-+ H2O

  • @dvijraicha4143
    @dvijraicha4143 2 месяца назад

    At 1:18:47, for part e), does it matter if you label CO + 2H2 as the products, rather than CH3OH? I found this question on CollegeBoard and found that the scoring guidelines said to do it the other way.

    • @dvijraicha4143
      @dvijraicha4143 2 месяца назад

      I went ahead and looked at the actual question. The prompt provides the reaction as CH3OH -> CO + 2H2.

      In this context she is balancing the chemical formula. There are 4 H's present in the product side, so 4 H's need to be on the reactant side to balance the mass

    • @inkbledi
      @inkbledi 2 месяца назад

      My logic is that it doesn't matter whether or not it's positive 2 or negative 2, as the guy above me said, as long as the charge is big it will have a higher attraction rate, correct me if I'm wrong though;;

    • @mr.snuffulmuffin6954
      @mr.snuffulmuffin6954 2 месяца назад

      This context is in regards to the ion-dipole attraction between a Cation and a H2O molecule. The more positive a charge on the cation, the stronger the attraction between the negative dipole on the Oxygen in the water molecule and the Cation as given by Coulombs Law.

    In the last question, since the solution is diluted doesn't that mean that it would allow more light to pass through? Since there are droplets of distilled water? So the measured asborbance would be too high than in reality?

    • @blankk24
      @blankk24 2 месяца назад

      I don't think the frosted sides mean dilution but that the light passing through gets absorbed by the frosted side AND the FeSCN making the results not accurate since light is getting absorbed by another substance as well so absorbance would be higher

    @academic-coach-youhyun What is the difference between ICE, ICF, and IMF tables??? I am on a tight line for the AP. By the way, I really appreciate your videos.

    • @academic-coach-youhyun
      @academic-coach-youhyun 4 месяца назад

      I(initial) C(change) E(equilibrium) is used when the reaction eventually reaches equilibrium. ICF(final) is used when the reaction goes to completion. To be honest, as for calculation you can use ICF instead of ICE. This is just an easy way for doing math and it's not some Chemistry concept. You won't get points off in the AP exam for using these two interchangeably.
