If we made the equation in the first part using lg would marks be deducted???
It just asked to form the equation and both lg and ln give same answers

wht did u get for a and b in bin exp q?

 

[Dark Destination]

What was the range for f inverse? and domain?

 

[Ram97]

wht did u get for a and b in bin exp q?

a=-3 and b=2

 

[Ram97]

What was the range for f inverse? and domain?

what did u get???

 

[Ram97]

Range for f is domain of f inverse and like wise

 

[Dark Destination]

what did u get???

Domain was x > -1

And range was from -infinity to +infinity

 

[Ram97]

Why did gf(x) have no solutions??
What abt differentiation???

 

[Dark Destination]

Why did gf(x) have no solutions??
What abt differentiation???

I wrote a lot of different stuff without thinking.
Wrote discriminant is less than zero
And also wrote 2x = x is not possible.. and stuff..

 

[Ram97]

What did u get for gf(x)???

 

[Ram97]

Domain was greater than 7
Range was greater than 2

It just asked to form the equation and both lg and ln give same answers

for one 2^x=0 is not possible and two
2^x=1
x=0 not in the domain hence no solutions of eq
and domain was transpose of range of f and f^-1 right?

 

[M.Omar]

What did u get for gf(x)???

why it,s not possible wala question?

 

[Dark Destination]

for one 2^x=0 is not possible and two
2^x=1
x=0 not in the domain hence no solutions of eq
and domain was transpose of range of f and f^-1 right?

I wrote 2x can not be equal to x because the domain is x>2

is this right?

 

[Ram97]

why it,s not possible wala question?

no the equation

 

[Dark Destination]

why it,s not possible wala question?

What was the range and domain for f inverse?

 

[M.Omar]

Domain was greater than 7
Range was greater than 2

can u elaborate ?

 

[M.Omar]

What was the range and domain for f inverse?

transpose of range and domain of and f^-1

 

[M.Omar]

no the equation

just asking..did ur comp pprs got cancelled or wht?

 

[Ram97]

can u elaborate ?

i got this for f inverse

 

[Dark Destination]

transpose of range and domain of and f^-1

What was it?

I wrote plus infinity to minus infinity, as the range.
And x> 1 as the domain.
