1. how can you simplify this expression:
(4-x^2) (1/3) (6x+1)^1/3 (-2x)/ (4x - x^2)^2
i totally dont know how to work this problem out can someone pls help me? Thanks
2. How do you find an equation for the left half of the circle given by (x + 2)^2 + y^2 = 9
3. How to find f(a +h) -f(a)/ h if h cannot = 0
for the folowwing:
f(X)= -x^2 + x +5
f(x)= 1/ x+2
I know for the first equation F(a+h)= -(a+h)^2 + (a +h) + 5 and f(a)= -a^2 + a +5 . I tried solving it but i cant get the answer from book. pls explain in details
for the 2nd equation f(a+h)= 1/(a+h) +2 and f(a)= 1/a+2 and im stuck do you find the common denominator, and if you do what would it be? thanks
