Continuity. When is f(x)={x^2-4x+3 when x≠0; 3 when x=0 continuous? We learn how to find the intervals on which f(x)={x^2-4x+3 when x≠0; 3 when x=0 is continuous. We will also classify the type of discontinuity when needed. The type of classifications for the function can be Continuous, has an Essential discontinuity, or a Removable Discontinuity. This is a great introduction into determining and classifying continuity. This is under the topic of Continuity with this free online math video lesson. #continuity #discontinuity #essentialdiscontinuity #removablediscontinuity #calculus #calculushelp #minutemath #onlinemathlessons

Relative Extrema. Find all points of relative minima and maxima of y=(2x-8)^(2/3). We learn how to find the relative minimum and relative maximum of y=(2x-8)^(2/3). We first find the derivative of the function. Then we find the critical points of the function. We then apply the first derivative test to see where the function is increasing and decreasing. This then helps us find where the function has a relative minimum or a relative maximum. We then use those x-coordinates and plug them into our original function to find the y-coordinate values. This then gives us all the points of relative minima and maxima. This is a great introduction into Relative Extrema. This is under the topic of Applications of Differentiation with this free online math video lesson. #relativeextrema #relativeminimum #relativemaximum #minima #maxima #calculus #derivatives #minutemath #calculushelp

Intervals of Increase and Decrease. Find the first derivative test of y=-x^3+2x^2+2. We learn how to find the x-coordinates of all critical points, find all discontinuities, and find the open intervals where the function is increasing and decreasing of y=-x^3+2x^2+2. We first determine where the function is discontinuous. We then take the derivative of the function to find its critical points. We then apply the first derivative test to see where the function is increasing and decreasing. This is a great introduction into the First Derivative Test.

? Welcome to our enlightening math tutorial video! In this session, we'll delve into the concept of the complement of an event and explore the probability of drawing a card from a deck that is NOT a heart. Whether you're a card game enthusiast or someone seeking to enhance your understanding of probability, this video is tailored just for you.
In this video, we'll address the following question:
? What is the probability of pulling a random card from a standard deck of playing cards, and it NOT being a heart?
Our expert math tutor will guide you through the step-by-step process of calculating this probability, demystifying the concept of event complements. By the end of this tutorial, you'll have a solid grasp of how to work with probabilities involving the "not" scenario, a valuable skill for various probability problems.
So grab your deck of cards, prepare to shuffle (or not!), and join us on this educational journey. If you find this video informative, please don't hesitate to give it a thumbs up and subscribe to our channel for more math-related content. If you have any questions or need further assistance, feel free to drop a comment below. Happy learning! ???
