After understanding the exponential functionour next target is the natural logarithm. The natural log gives you the time needed to reach a certain level of growth. Read more about e. Natural Log ln is the amount of time needed to reach a certain level of continuous growth Not too bad, right?

Find the slope and the y-intercept of the line. This example is written in function notation, but is still linear. As shown above, you can still read off the slope and intercept from this way of writing it.

We can get down to business and answer our question of what are the slope and y-intercept. In this form, the slope is m, which is the number in front of x. In our problem, that would have to be 2. In this form, the y-intercept is b, which is the constant. In our problem, that would be The answer is the slope is 2 and the y-intercept is Note how we do not have a y.

This type of linear equation was shown in Tutorial If you said vertical, you are correct. The graph would look like this: Note that all the x values on this graph are 5. Well you know that having a 0 in the denominator is a big no, no.

This means the slope is undefined. As shown above, whenever you have a vertical line your slope is undefined. Looking at the graph, you can see that this graph never crosses the y-axis, therefore there is no y-intercept either.

Another way to look at this is the x value has to be 0 when looking for the y-intercept and in this problem x is always 5. So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist.How do I find a quadratic equation given 2 points and a maximum (max y coordinate)?

So you need three points to determine values of a,b,c. Writing Quadratic Equations. k Views · View Upvoters. John Marsh, Math Tutor, Chemistry Tutor. Answered May 10, · .

The Happiness Equation: The Surprising Economics of Our Most Valuable Asset [Nick Powdthavee] on r-bridal.com *FREE* shipping on qualifying offers. This intelligent and entertaining book shows how the scientific study of happiness is changing the field of economics—and the world! —Daniel Gilbert.

Given the following points on a parabola, find the equation of the quadratic function: (1,1); (2,4); (3,9). By solving a system of three equations with three unknowns, .

Just as a quadratic equation can map a parabola, the parabola's points can help write a corresponding quadratic equation. With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and write the parabola algebraically.

In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula. Anytime we need to get the equation of a line, we need two things. Jul 24, · Title says it all.
