Hello! I need help with some questions I have to do. Any help would be much appreciated.
A) Determine the inverse of y= 5x21-3x-4
I got the answer:
log2(x+4/5)-1 = y
That doesn't seem right to me. :/
B) What are the intercepts of; y= (x-a)2(x+2a) ; a>0
I got to y= (x3+2ax2)-(a2x-2a3)
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 2j(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; ~ f1(x)=log2x; (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!
