I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observati...
Find the equation of this function table. Find the transform of the function, F(t)= 7e^3t sin 4t, by use of a table. Let be the functions in the table below | x | f(x) | g(x) | f'(x) | g'(x) | 1 | 3 | 2 | 4 | 6 | 2 | 1 | 3 | 5 | 7 | 3 | 2 | ...
Find the equation of the line that is normal to the function at x=π6x=π6. Step 1 Find the point on the function. f(π6)=cosπ6=3√2f(π6)=cosπ6=32 The point is (π6,3√2)(π6,32). Step 2 Find the value of the derivative at x=π6x=π6. f′(x)=...
Plugging into the original equation gives: C = Y1 - AX1^2 - BX1 This all looks horrible, but we have the values for Y1, Y2, Y3, X1, X2, and X3 so we just plug them in. The example does that to find A, B, and C. It then graphs the function so you can see it passes th...
How to Find the Amplitude of a Function (Sine Function) Examples Lesson Summary Frequently Asked Questions How do you find the amplitude of a sine curve? The amplitude of a sine curve can be found by taking half of the difference between the max and min values. If the equation y = asi...
Therefore, to find the location of the local maxima and local minima you have to solve the equation f'(x) = 0. Therefore you have to first find the derivative of the function. If you are not familiar with the derivative, or if you would like to know more about it I recommend reading...
In order to identify the equation of a tangent line to the function f(x) at a particular given point xo, we have to: Identify the derivative of the given function f′(x) Evaluate the derivative at the given point, f′(xo) Find the value of the function f(x)...
The equation for a line is of the form y=mx+b, where m represents the slope and b represents the intersection of the line with the the y-axis. This article will show by an example how we can write an equation for the line that has a given slope and pass
I want the user to be able to insert his own equation (e.g. a*x.^2 + b*x + c) to be used to plot the function. I have already defined the variables a, b and c (to which it will be limited) and have everything working if I put y=*equation* in the .m file. How ...
a lot of quadratic functions, but it also might be very difficult to see what to do. We have a quadratic function ax^2 + bx + c, but since we are going to set it equal to zero, we can divide all terms by a if a is not equal to zero. Then we have an equation of the form...
