First of all , I think you meant f(x) = 1/(x+5) the difference quotient is (f(l+h) - f(6))/h = (1/(11+h) - 1/11 )/h = (11 - 11 - h)/(11(11+h) (1/h) = -1 / (11(11+h)) I notice another error is your typing you probably meant to type: ..... can be simplified to -1/(a(h+b) ) ...

f(x) = 1/(x+11) where x is not 11 or -11. It looks like it ought to be true for x=11 as well, except that at x=11, we have f(x)=0/0. So, the function is continuous on (-oo,-11) (-11,11) and (11,+oo) While the limit from the left and right at x=11 is 1, the function is not ...

Start by converting 2 3/4 to an improper fraction. (3+2*4)/4 = 11/4 Divide 11/4 by 1/2. (11/4)/(1/2) = (11/4)*(2/1) = 11/2. Convert back to a mixed number. 11/2 = 5 1/2. The cook cannot bake half a batch of muffins. Round down to 5 batches.

**Maths, find the Exact Value**

2/3 + 3/4 - 2/11 - 5/21 3*4*11*7 = 924, so if we use that as our common denominator, the numerators add up to: 2*(4*11*7) + 3*(3*11*7) - 2*(3*4*7) - 5*(4*11) = 921 921/924 = 307/308

You would complete the square, but let's first clean it up a bit f(x) = 3x^2 - 12x + 11 now ... = 3(x^2 - 4x + ..... ) + 11 = 3(x^2 - 4x + 4 - 4) + 11 = 3((x-2)^2 - 4) + 11 = 3(x-2)^2 - 12 + 11 = 3(x-2)^2 - 1 up to you ....
