[ALGEBRA II] Interval Notation
[Grade 12: AP calc AB prep] I'm kind of rusty so what does domain and range, and interval notation mean?
[Math Pre Calc Help] find the domain of the functions then write your answers using interval notation
[AFDA] how would i calculate the domain in interval notation for these two functions?
domain means all the numbers you can input for x.
When you are dealing with fractions like in "c," you can not have the denominator equal to 0. So any value of x that would make the denominator 0 will need to be excluded from your domain, while all other numbers would be in your domain.
For "d," the number underneath the square root sign must not be negative. So any value of x that would make the expression underneath the radical negative will not be in your domain.
Do you understand interval notation?

Hey Reddit, I'm pretty sure this is close to right, however, I'm not sure how to write it.

A graphing calculator is recommended.
In this problem you are asked to find a function that models a real-life situation and then use the model to answer questions about the situation. Use the guidelines on page 237 to help you.
A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 14 in. by 30 in. by cutting out equal squares of side x at each corner and then folding up the sides (see the figure).
I'm trying to solve (b): (b) Find the values of x for which the volume is greater than 210 in3. (Round your answers to three decimal places. Enter your answer using interval notation.)
Basically, I took what I wrote in standard form, solved/converted the inequality, and plugged it into a graphing calculator and mathway.
4x3 - 88x2 + 420x > 210
After solving/converting, the answer I received was: (0.565, 6.029) U (15.405, infinity sign)
