• f(x)=5x^2-3x+7, and f(g(x))=40-11x^2-8x^4. How do I find the sum of all possible coefficients of g(x)?

f(x)=5x^2-3x+7

f(g(x))=-8x^4-11x^2+40.

Should I let x^2 be a new variable? Where do I start?

• if f(x)={x+5, if x-<-1,            {cx^2, if x>-1 find c so that the limit of f(x) as x approaches -1 exists.?

it's a piece-wise function, I tried my best to show that, sorry.

• Evaluate the following limits.?

a) as x approaches 0, of the function (cos x tan x)/2x.

b) as x approaches 6 of the function (sqrt(x-2)-2))/x-6

c) as x approaches 1, of the function ((root x)-1))/(cube root x)-1
