Question 61000: I received help yesterday(11/11) on these problems and think I understand. I have submitted my attempts at some to see if I have the right idea and a few that still escape me. Some seem pretty straight forward now but others elude me. Thanks again for such timely help.
For the following, letf(x)=x+5; let g(x)=x^2^-2; let h(x)=-3x
for h{f(4)} I set 4=x, the value of f(4) then being 9; the expression h(9) would then be -27???right???
for g(x+3), I set (x)=x+3 and then the value of g(x+3) being x^3^+3x^2^-2x-6???
I lost it on the following and need help:
1. Same parameters (f-g)(x)
2. h(2x^2^+4x)
The last problem has nothing to do with the parameters above. It has just given me fits.
3. 5x^3/2^-25=0
Thanks in advance for your help and this great program.
