Answer:
y1=log (x+3) / log 4, y2= log (2+x) / log 2
Step-by-step explanation:
4^y = x + 3
2^y = x + 2
log_4(x + 3 ) = log_2 (2 + x )
log_4( x + 3 ) = y
log_2 (2 + x ) = y
Work Shown:
Solve for y. Then replace y with f(x).
Effectively this involves adding 1000 to both sides and subtracting 680x from both sides, afterward we divide both sides by 10 to isolate y.
