Problem 13 (9 point) Circle your answer for the following statement (True or False). If it is true, explain why. If it is false, explain why or give an example that disproves the statement. To get a mark, you need to give an explanatio.

If a statement is true, prove it. If not, give an example of
why it is false. Please neatly and carefully show all necessary
work.
4.If f :RR is such that both (0,0) and f(0.v) are continuous at (0,0), then f(x,y) is continuous at (0,0). 5. If f posses all of its directional derivatives at (a, b), then / is differentiable at (a,b). 6. If fr and fy both exist at (a, b), then all other directional derivatives exist at...
I'm stuck on this question, please help!
Question 1. Consider the following claims: (1) So g(x) f(x)dx = SØg(x)dx · SOF(x)dx holds for all f and g continuous. (2) If f(x) is such that So f(x)dx = 0 then f(x) = 0 for all 0 < x < 1. (4) If f is continuous in [0, 1], then is bounded, independently of the value of n. The sum of all correct statements equals:

Function 1:
Write a function that accepts an integer argument and returns
the sum of all the integers from 1 up to the number passed as an
argument. For example, if 50 is passed as an argument, the function
will return the sum of 1, 2, 3, 4, ... 50. Use recursion to
calculate the sum. Demonstrate the function in a
program.
A sample...
