Hii

Hi, nice video. I recommend you also to explain how to plot polynomials of multiple variables. It would be great)

The equation in the comprehension question should be x^4 + 5x^2 + 4 = y because x^4 + 5x^2 + 4 = 0 does not contain y, and is only used to find the x-intercepts; it is not the equation that we actually want to graph, which must contain y for the given answer.

Thank you very much professor

There is a small error in the video: when he says that you can also use the y-intercept, he puts the y-intercept of the function somewhere around -2/3, but if you actually calculate the y-intercept by replacing all x'es with a 0, you can see that the y-intercept is (0, -3), so the drawing is incorrect, the extrema of the function are way more outspoken.

you just explained everything my math teacher failed to do in a semester lol. thanks

Great explanations But 😄😄 how did you study on your own to understand at such deeper level?!!😁😁😁(aka your study tricks)

has to be y=4 specifically on x=0 on the comprehesion test or nah? and how do i get 4 do i just plug in 0 on the x

@SephBustamante

like on the (x+1)(x-1)(x+2)(x-2) because if you plug 0 in you do get +4

You can also use the quadratic formula just rearrange it like this and you would be able to find x^2. (x^2)^2 - 5(x^2) + 4 = 0

I don't mean to be pedantic here, but if you graph the equation shown at 8:18, x^4 - 5x^2 + 4 = 0, you're going to end up with four vertical lines with x-intercepts at x={-2,-1,1,2}. It seems like what you are really asking your students to do is sketch the graph of f(x) = x^4 - 5x^2 +4.
