Yes f is a function. This is because each element of its domain A is assigned to exactly one element…

For each of the following expressions, write functions f1, f2, f3, and f4 such that the evaluation of each expression succeeds, without causing an error. Be sure to use lambdas in your function definition instead of nested def statements. Each function should have a one line solution. f1 takes in nothing and returns 3. f2 takes in nothing and returns a function that takes in nothing and returns 3. f3 takes in nothing and returns a function that takes in 1 value and returns that same value. f4 takes in nothing and returns a function. This function takes in nothing and returns another function. This next function takes in a value and returns yet another function. This final function takes in nothing and returns the value passed into the previous function (if this explanation is confusing, have a look at the doctest, and it might be more clear). def f1(): >>> f1() 3 |||||| "*** YOUR CODE HERE ***" def f2(): |||||| >>> f2() () 3 |||||| "*** YOUR CODE HERE ***" def f3(): |||||| >>> f3() (3)…

Create the following in R programming language: a function which contains the following: – takes as input a data frame, and the two elements of a frame that you want to model –Plot the data fit with a smoothing spline with the default cross validation, vs the smoothing spline with 2 degrees of freedom (linear fit). –Test the difference of fit using the F test –Plot the normal quantile quantile plots for the residuals.
Trucks take up more space on the road and are slowed down more by hills and steep inclines. Each truck on the road is translated into a number of cars using the following table. Car Terrain type equivalent of one Truck level 1.7 rolling 4.0 mountainous 8.0 Write the function car_equivalent_factor(terrain_type) that takes a string containing one of the three terrain types and returns the number of car equivalents for a truck on the given terrain. You function should always return float Notes: • You can assume that the function will always be called with one of the three valid terrain types. For example: Test Result factor = car_equivalent_factor('level') 1.7 print(factor) Answer: (penalty regime: 0, 10, 20, ... %) Ace editor not ready. Perhaps reload page? Falling back to raw text area.
