If `f: RR -> RR` is defined by `f(x)={((x-2)/(x^2-3x+2), if x in RR\\{1, 2}), (2, if x=1), (1, if x=2):},` then `lim_(x->2) (f(x)-f(2))/(x-2)`

If f, RR to RR is defined by f (x) ={{:((x-2)/(x ^(2) -3x+2)"," ,"when " x in RR-{1","2}),(2",","when" x=1),(1",", "when" x=2):} then lim _(xto2) (f(x) -f(2))/(x-2) is equal to-

If f: RR to RR is defined by f(x)={{:(,(x+2)/(x^(2)+3x+2),"if "x in R-{-1,-2}),(,-1,"if "x=-2),(,1,"if "x=-1):} then is a continuous on the set

If the function f: R to R is defined by f(x) =(x^(2)+1)^(35) for all x in RR then f is

If f: [-6, 6] -> RR is defined by f(x)=x^2-3 for x in RR then (fofof)(-1)+(fofof)(0)+(fofof)(1)=

If f,g : RR to RR are defined by f(x) = |x| +x and g(x) = |x|-x, find g o f and f o g.

If f: RR -> RR defined by f(x) = {(a^2cos^2x+x^2sin^2x;, x 0):} is continuous at x=0.

Let f : RR to RR be given by f(x) = x+ sqrt(x^(2)) is
