Questions
- Let #RR# denoted the set of real numbers. Find all functions #f:RR->RR#,satisfying #abs(f(x) - f(y)) = 2 abs(x-y)# for all #x,y# belongs to #RR#.?
- What are the asymptotes of #f(x)=(4tan(x))/(x^2-3-3x)#?
- Is that true to say: For every set A defined by A={ A : ∅∉A } then the Cardinality of A equals to |A|-1 ?
- What is the difference between a vertical and horizontal asymptote?
- What are the asymptotes of #f(x) = (2x-1) / (x - 2)#?
- How do you decide whether the relation #x^2 +y^2 =16# defines a function?
- Do asymptotes always converge to a value?
- What are the horizontal and vertical asymptotes of: #f(x)=xtan(x)#?
- What are the asymptotes of #f(x)=(1/(x-10))+(1/(x-20))#?
- How do you decide whether the relation #x - 3y = 2# defines a function?
- Does #(0,4)# make the equation #y =x# true?
- Is #(-4, 2)# a solution of #2x-5y=10#?
- Given #y= x ^ { 2} + 2x # , what are the values of y(x) for x = -3, -2, -1, 0, 1, 2 and 3?
- The function f is defined by f:x =6x-x^2-5 Find set of values of x for which f(x)<3 I have done finding x values that are 2 and 4 But I don't know which direction inequality sign should be?
- For the function #f(x) = 1+3x-x^2#, what is #f(t-2) + c#?
- What is the ordered pair of x+y<6; y≥ 7x-3?
- A function is defined by f(x), value given when f(-2)=9? Hence find f(x)=0?
- The function #f# is defined by #f(x)=1-x^2#, #x sub RR#. Show that #f# is NOT one-to-one. Can someone help me please?
- Even though I know some stuff, I am not to keen on functions. What do we do when f(x)=x^2 - 3x + 4, and I need to find f(2x). How do you do it? Don't give the answer, just wondering how, not what!
- You are planning a 9 day trip to Texas. It will cost approximately $350 per day in Houston and $400 per day in San Antonio. If your budget for the trip is $3400, how many days can you spend in each place?
