Re: Maths help available here!!! Stuck somewhere?? Ask here!

if h is a function where h(x)=4x+1 and g[h(x)]=4x+2 find the function g(x)

through quick deduction you can probably figure out that g(x)=x+1

but what is the proper process of solving this?

in need a step by step guide for this
thank you
btw an answer today will be appreciated

Re: Maths help available here!!! Stuck somewhere?? Ask here!

Hi scafolon40,

I can't think of a step by step solution to this problem because there is too many variation to gx.
It can have a varying coefficient of x terms with different powers.
It can also be a combination of different x terms.
Hence, I feel that this question is testing deduction skill.

My two cents' worth.

Re: Maths help available here!!! Stuck somewhere?? Ask here!

Hey,
I'd like some notes about: 1- one-one functions; 2- domain; 3- range.
I get them right at times, but it always confuses me. I'll be of great help if you give me an explanaiton with examples :)
Thanks.

Try to change gh(x) function to get h(x)

gh(x)=4x+2
gh(x)=4x+1+1 where 4x+1 is h(x)
gh(x)=h(x)+1
g(x)=x+1

This question is simple.
asinbx+c means that you have to multiply every value of sinx by a and then add c to it. like sin90 is 1 so (1xa)+c. But when you multiple sin0 which is zero like (0xa)+c you will get c. Use this principal to calculate a and c in the question.
so sin0=0
a(sin0)+c=3
a(0)+c=3
c=3

sin90=1
a(sin90)+3=9
a(1)+3=9
a=6

now to calculate b, use period=2pi/coefficient of x
so pi=2pi/b
b=2
