How do you graph a piecewise function? What do you need to know to graph the linear inequalities -3x-5y-15 Given the equation y=-4x+2.5 predict the y value when x =-1.75 What is the value of y-x, if x+2=y? How does the multiplicity of a factor affect the graph at the relate...
In summary, the problem is that the homework statement is giving a piecewise function which has an on/off moment at 4 and 5 seconds, but the graph does not match. The student is struggling to solve the equation for f(t) which should be written as a function of unit step functions and...
In summary, to solve the initial value problem with the given piecewise function, first solve for the case where 0 < k < 4, and then use that solution to find A and B in order to solve the problem for the general case. Homework Statement Consider the initial value problem y'' +1...
I know how to apply piecewise functions with numbers, but it does not allow me to use variables on the start-end intervals or in the "function", where you specify the function for each tram. Do you know a way to do it? I really need to define a fu...
Learn about piecewise functions. See a piecewise function example to learn how to write a piecewise function and to learn about evaluating piecewise functions. Related to this Question A cubic spline is defined by S(x) = \left\{\begin{matrix} 1+a(x-1)-b(x-1)^{3}, (1,2) 1+c(x...
The problem you have described is not necessarily a problem about creating a piecewise function, but it can written down as one. To do so we need to: assume that Jonas sells the cups of coffee at a constant rate for each of the listed time periods, define the base variable (current tim...
I have a symbolic function r and am trying to plot it using fimplicit but I keep on getting an error in Matlab. I have tried switching up the symbolic r function, but it isn't working no matter what I try. Any suggestions? This is a school assignment, so no complete answers. ...
We need to emphasize here that, apart from Courtney [3] this problem has not been considered elsewhere. There are papers [1] where one recovers a function on {{\mathbb {T}}} which is piecewise constant (or even piecewise a polynomial) with the correct number of samples (roughly equal ...
The cosine function is common in math, so is important to recognize it and know how to represent it on a graph. Explore the steps to solve and graph cos(x), including how to do so with a sine function. Steps to Solve Cos(x) To graph y = cos(x), we need to be familiar with...
