I believe that there is a mistake on Example 9. Since f is defined on [-4, 4], choice A is not in the domain. I believe that the answer should be B.

@MrHelpfulNotHurtful Ай бұрын

Thanks!

@MrHelpfulNotHurtful Ай бұрын

Just looked it up. The College Board said the answer is A. They say that even though the domain of f(x) is [-4,4], the domain of the composite function f(g(x)) is [-7,1].

@barryzions264 Ай бұрын

@@MrHelpfulNotHurtful First off, I love the way that you explain these to the kids, and I have your site(s) as a resource for my students. I just like to check all the resources that I give them to avoid confusion. Look at the order of the solutions. I have answer A, but your answers are in a different order. I also checked with college board (2.7. Question #4 and with another teacher in my district) and they both said that the domain is [-4, 1] Given f(g(x)): 1. Find the domain of g. 2. Find the domain of f. 3. Find those inputs, x, in the domain of g for which g(x) is in the domain of f. That is, exclude those inputs, x, from the domain of g for which g(x) is not in the domain of f. The resulting set is the domain of f(g).

@MrHelpfulNotHurtful Ай бұрын

@@barryzions264 I’m so glad you are finding my videos helpful! I make them for my students but I always hope others will use them too. Go to AP Classroom and select the Course Guide. Then select Unit 2. Then scroll down to 2.7 Composition of Functions and expand that. Below the daily videos there are six MCQs. The question we are discussing is the fourth one (Composition - graphical). Open that one. Now click on the arrow on the right side of the screen that says question scoring details to expand the solution window. Answer A (same order as my video) will highlighted green with a check mark indicating A is correct. Scroll down to the bottom of the screen. It says “Answer A. Correct. This is the result of translating f 3 units left. Although the domain restriction of f is [-4,4], the domain restriction of f(g(x)) is [-7,1] because the composition is a horizontal translation of f.” Let me know if you are seeing something different when you pull it up. 🤔

On the 10th question couldn't we just multiply the percentage of the people who buy a donut and the percentage of people who buy coffee

@MrHelpfulNotHurtful 2 ай бұрын

Multiplying the two percentages will only give you the correct probability of two events happening when those two events are independent. We cannot assume these events are independent. The mention of a percentage of people who get a coffee or a donut basically tells you that’s these events are not independent and you must use the formula I used instead.

If you are asking how you find the percentage without using the z-score table, you can’t. The table is the only way to turn a z-score into a percentage.

@kberkman 2 ай бұрын

@MrHelpfulNotHurtful so we figured out how to solve it using a calc... but I imagine to get the tables you have to use a formula. I just want to be able to figure out how it's done (like with z-score u can use a table too but there is a method to the madness)

Thanks for the video but I suggest using the intersecting chords theorem where the second chord is the diameter (d) passing through P, M and O to the other side of the circle ( lets call it Q) The theorem basically says that the lengths of the chord segments for both chords on each side of the intersecting point when multiplied together are equal. So in your example: AM × MB = PM × MQ 5 ×5 = 3 × (d-3) 25=3d-9 34=3d 34/3=d=2r r=34/6=17/3 Same answer but less constuction and simpler algebra.
