Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question. Please edit your question to include words for symbols and any other relevant detail.
Also, it would help if you did not simply define a function but specified what you wanted done about it!

f(x) or y = 6x + 4Well, y= mx+ b This function is simplified already.
You can use the quadratic formula for this.
If you mean: f(x) = 3x^2 +6x +8 and x has a given value of 4 Then the function of x is: f(4) = 3*16+6*4+8 = 80
If you mean: 9x squared+6x+1 = 0 then x = -1/3 and x = -1/3 therefore the quadratic equation has equal roots

-6x-32 = 2x -6x-2x = 32 -8x = 32 x = -4
f(x) =6x-4 f(x) = 6(8)-4 f(x) =48-4 f(x) =44
A function f crosses the x axis where f(x) = 0. So the function f(x) = x^2-6x+8 crosses the x axis where x^2-6x+8 =0. x^2-6x+8 can be factored: (x + 4) (x -2) = 0 When x = -4, f(x) = 0. and When x = 2, f(x) = 0.
x3 - 7x2 + 6x = x(x2 - 7x + 6) = x(x2 - x - 6x + 6) = x[x(x - 1) - 6(x - 1)] = x2(x - 1) - 6x(x - 1) = (x2 - 6x)(x - 1)
Add 1 to the coefficient and divide by that term. int[f(X) by the power rule is this.......X(n + 1)/nint(6X)= 6/2(X2)= 3X2 + C--------------
6x-1 = 1169 6x = 1169+1 6x = 1170 x = 195
f(x) or y = 6x + 4Well, y= mx+ b This function is simplified already.
6x - 10 = 32 +10 +10 6x =42 x= 7
4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x4x2 + 5x + 1 - 4x2 - 6x = - x + 1 or 1 - x
You can use the quadratic formula for this.
