You can probably look up a answer key for that worksheet. ;)
Replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)
f(x)=x-1
y=x-1
x=y-1
x+1=y
x+1=f⁻¹(x)
f⁻¹(x)=x+1
Answer: i took the test and got it right
D (0.55,0.75)
Step-by-step explanation:
A) A= 5000 x .0325 ( 31)
A= 5,037.50
.0325 = 3.25%
31 years 2021-1990 = 31
43 is the median, the mean is 36.6 (36.57 rounded up) and since none of the numbers repeat, there isn't really a mode.
Hope this helps
