Hello! I need help with some questions I have to do. Any help would be much appreciated.

**A) **Determine the inverse of

*y*= 5x2

^{1-3x}-4

I got the answer:

__log___{2}__(x+4/5)-1__ =

*y*
-3

That doesn't seem right to me. :/

**B) **What are the intercepts of;

*y= (x-a*)

^{2}(

*x*+2

*a*) ; a>0

I got to

*y= *(

*x*^{3}+2

*ax*^{2})-(

*a*^{2}*x*-2

*a*^{3})

Not sure what to do now...

**C) **This is a weird one. :/ Explain how a relation could be restricted to a function.

Da fuq??? O_o

**D) **What transformations have been made to

* j(x)* to get 2

*j*(1-

*x*)?

Would that be; dilated vertically by 2, translated 1 upwards, and reflected in the

*x*-axis???

**E) **The

** Function**,

**Point**, and

**Asymptote** of; ~ f

_{1}(

*x*)=log

_{2}*x*; (1,0);

*x*=0; ~ when it is translated four units left, and one unit up???

Any help with any of the questions would be beyond fantastic!
