but you’ll rarely be dealing with simple equations in calculus. Most graphing calculators have the ability to solve for intercepts (you can find a simple online calculatorhere). However, in many cases (especially in elementary algebra or pre-calculus), you’ll need to find the solutions alge...
So the graphical concept ofx- andy-intercepts is pretty simple. The problems start when we are required to try to deal with intercepts algebraically. To clarify the algebraic part, think again about the axes. When you were first introduced to the Cartesian plane, you were shown the regular nu...
How to find a in a parabola Find the coordinates of the point(s) on the parabola y = 4 - x^2 that is closest to the point (0, 1). Algebraically determine the equation of the parabola that passes through each of the points (-1, 11), (1, -3) and (3, 7). How to find the...

This means you need to set your equation equal to zero and solve for x. That seems easy enough, right? Now that might be a problem, because sometimes — finding the exact solution (roots) of an equation algebraically is easier said than done. So when faced with solving an equation that...
Using math software to find the function a. Wolfram|Alpha ThisWolfram|Alpha searchgives the answer to my last example. b. Excel You could use MS Excel to find the equation. Enter the points in cells as shown, and get Excel to graph it using "X-Y scatter plot". This gives the...
Solve: (𝒙−𝟐) 𝟐 +𝟓= 𝟑 𝒙 For now you won’t be able to solve this problem algebraically. Follow the instructions on the next slide to use the “intersect” key on your calculator. To accurately find the coordinates of the point where two functions intersect, perform the...
Since we are not interested in other covariates, we omit them and describe this model algebraically as $$ {\displaystyle \begin{array}{c}{y}_{ij}\sim \mathrm{Binomial}\left(1,{\pi}_{ij}\right)\\ {}\mathrm{logit}\left({\pi}_{ij}\right)=\log \left(\frac{\pi_{ij}}{1-{\pi...
