Exponential Function Word Problems

In this video, we'll tackle real-world problems that can be modeled using exponential functions. Understanding how to apply exponential functions to word problems is a critical skill that will help you see the practical applications of what you're learning in class. We’ll start by focusing on setting up exponential equations from word problems as that will set the stage for the rest of the problem. Identifying key features and unknown variables in each word problem will give us the components we need to build our exponential equation. We then use this exponential function to answer the question being asked in the word problem. Toward the end of the video we add in word problems that are solved using linear equations to add another layer of decision making to the process of solving word problems. A discussion on rounding will also be had throughout this video. With clear explanations and practical examples, you'll gain the skills needed to confidently solve word problems involving exponential functions.

Thanks this really helped me before i took my finals i will share this with my friends

[nilaydesaiii]

Thanks for this, i really needed this to understand it better since I am in 8th grade and in honors Algebra 1

[brookevetter]

for real the only vid I watched that actually helped me understand and ur voice isnt annoying like the rest. u the goat djones

the line, ''we either have a turtle, or we don't have a turtle" made me laugh

[IsabellaJohleeOpulencia]

is there a way to graph this and find its intercepts?

What about for the first problem? Why did you round up if you were referring to the members of the gym? Isn't that supposed to be 146 only? And should be “we either have a member, or we don't have a member, ” too?

when to use the other formula i.e. Q'=Qe^kt (where Q is the initial amount and k is the percentage of increase and t is the time)???

Guys, I ACTUALLY UNDERSTAND!! This just confirms that my math teacher is poop. Thanks so much for this wonderful video 🫶🫶

The third and fourth question are wrong. For instance the fourth question where you are asked to find the population of USA in 2007, it says there is an increase of 0.85% ANNUALLY meaning that 0.85% is increased every year. the answer is 434395 I believe

I never learn this before my goal passed my GED 🎓

I can’t understand I have tast tomorrow
