👉 Learn how to identify transformations of functions. Transformation of a function involves alterations to the graph of the parent function. The transformations can be dilations, translations (shifts ...

Description: 👉 Learn how to write the equation of a polynomial when given rational zeros. Recall that a polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are ...

There are a series of points rising from left to right. If you had to describe this graph, you’d likely say something like, ‘as the horizontal (x-axis) values increase, the vertical (y-axis) values ...

Photoplethysmography (PPG) is a non-invasive optical technique widely used in the study and monitoring of the pulsations associated with changes in blood volume in a peripheral vascular bed. Over the ...

Jacques Verstraete and Sam Mattheus, researchers at the University of California, San Diego, have made a significant breakthrough in Ramsey theory by solving the r(4,t) problem, a challenge that has ...

Ramsey problems, such as r(4,5) are simple to state, but as shown in this graph, the possible solutions are nearly endless, making them very difficult to solve. (cr: Jacques Verstraete) We’ve all been ...

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...
