Given, f(g, x, y) = g(x, y)
Type of the function is: f = fn
We can write it as: ('a * 'b -> 'c) * 'a * 'b -> 'c
what polytype will infer for the followinf function? f(g, x, y) = g(x, y)
6-4 (a) The function g(x) is monotone increasing and y = g(x). Show that F(x) if xy(x, y) =İF,(y) if y>g(x) y<g(x) xytty (b) Find Fxy(x, y) if g(x) is monotone decreasing.
23. (a) Show that a function f : X → Y is a surjection if and only if there is a funct io On g : Y → X such that fog = idy. (b) Show that a function : X → Y with nonempty domain X is an injection if and only if there is a function g : Y → X such that g o f-idx. How does this result break down if X = φ? (c) Show...

6. We say f(x,y) is a function of x +y if f(x,y) = g(x+y) for some one variable function g. For example, sin(a+y) and ex+w' are functions of x + y. (a) Find a condition on the differential equation A(x, y) + B(x,y) = 0 so that it may be transformed into an exact equation via an integrating factor (+ v). (b) What is a formula for this integrating factor. (c) Use this strategy to solve (7x*...

Write a MATLAB function with header [y] = mySplit(f,g,a,b,x), where fand g are handles to functions f(x) and g(x), respectively. The output argument from this function y should be: ( f(x) g(x) ( f(x) * g(x) if if y = b<x sa a < x otherwise Hint: • a, b are integer numbers with a > b. • f(x) = x*sin(x) • g(x) = cos(x)/(x²+1)
Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] (96%), f(u) = ( 0,- 1 x)

2) Show that a Green's function G(x,y) satisfying the problem a2G = 8(x - y), G (0,y) = 6,(1, y) = 0 does not exist, but a modified Green's function Ĝ(x,y) satisfying a2G 22 = (x - y) -1, G.(0,y)=G.(1,y) = 0 does. How would you use G to solve problem (1) when f satisfies the condition that you found for a solution to exist? Hint: is f(x) = f(u) (8(x - y) - 1) dy?
