I am getting old...

f(x^2 - 2) - g(x - 5)
((x^2 - 2) - 5) - ((x - 5)^2 - 3)
x^2 - 7 - (x^2 - 10x + 25 -3)
x^2 -7 - x^2 + 10x - 25 + 3
10x - 29

???

I do not know... I have not touched math for more than 10 years other  ...

you're correct!

celeron_266

ok lets see...math 12....transformation chapter correct?

versa's solution is correct

myversa

f(x^2 - 2) - g(x - 5)
((x^2 - 2) - 5) - ((x - 5)^2 - 3)
x^2 - 7 - (x^2 - 10x + 25 -3)
x^2 -7 - x^2 + 10x - 25 + 3
10x - 29

???

I do not know... I have not touched math for more than 10 years other than simple calculations...

Stupid question, but 呢題點做?

If f(x) = x - 5 and g(x) = x^2 - 3 determine:
f(x^2 - 2) - g(x - 5)

It's supposed to be really easy but I totally forgot how to do it when I got home after class...

i thought you need at least one math course..

Since when?
I want to give up math too but can't... at least a couple more months to go for me (if not taking Math 12)

o in college/univ

studying arts in ubc
don't really need math

celeron_266

if you dont wanna go to a university giving up math 12 is fine....if not......you better take it...
