Which of these pairs of functions are inverse functions?
o fir)=25–1+1 and g(x) = log2 (1-1)—1
o flas= }{in()-1)
}{in() –1) and g(z)= 2e25+1
o fix) = 4in(52) and
e21
8
gif)=e
o flr)=109–10—10 and g(x)= log2 (x+10)—10

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

0.50 , 0.75

step-by-step explanation:

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
