Functions are a way of describing relationships between certain variables in an equation. In college algebra, we use functions to model real-world situations. For example, we might use a function to model the relationship between the amount of money we spend on gas and the number of miles we can drive. Functions can be linear or nonlinear. Linear functions have a straight line graph, while nonlinear functions have a curved line graph. College algebra is all about understanding how functions work and using them to solve problems.

How to solve mode: The mode is the value that appears most often in a set of data. To find the mode, simply order the values from smallest to largest and count how many times each value appears. The value that appears the most is the mode. For example, in the set {1, 2, 2, 3, 3, 4}, the mode is 2 because it appears twice while the other values only appear once. To find the mode of a set of data, follow these steps: 1) Order the values from smallest to largest. 2) Count how many times each value appears. 3) The value that appears the most is the mode.

Geometry is the math of shapes and solids. In a right triangle, the longest side is opposite the right angle and is called the hypotenuse. The other two sides are the short side and the long side. To find x, use the Pythagorean theorem which states that in a right angled triangle, the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse. This theorem is represented by the equation: a^2 + b^2 = c^2. To solve for x, plug in the known values for a and b (the two shorter sides) and rearrange the equation to isolate c (the hypotenuse). For example, if a=3 and b=4, then c^2 = 3^2 + 4^2 = 9 + 16 = 25. Therefore, c = 5 and x = 5.

Completing the square is a mathematical technique that can be used to solve equations and graph quadratic functions. The basic idea is to take an equation and rearrange it so that one side is a perfect square. For example, consider the equation x^2 + 6x + 9 = 0. This equation can be rewritten as (x^2 + 6x) + 9 = 0, which can then be simplified to (x+3)^2 = 0. From this, we can see that the solution is x = -3. Completing the square can also be used to graph quadratic functions. For example, the function y = x^2 + 6x + 9 can be rewritten as y = (x+3)^2 - 12. This shows that the function has a minimum value of -12 at x = -3. By completing the square, we can quickly and easily solve equations and graph quadratic functions.

The app is great a very useful. 2 stars (the app is worth 5 but because of that now after editing you get 4) because of that stupid way you implemented the premium feature, I mean adding a premium mode to your app is perfectly okay if you add new features and then asking for money but taking something old and asking for money for that is complete laziness and lack of interest from the developers!

This app helps me solve every single equation I am stuck with by showing me the steps I need to take in order to solve it. Congrats to the developers behind it! I love using this app for school problems I don't know but it will be good if it can solve word problems
