Step-by-step explanation:
I think it is # 2. Hope this helps;)
First of all, find f ⁻¹ (x), or the inverse function like so:
y = log(3x + 12)
e^y = 3x + 12
3x = e^y - 12
x = 1/3 (e^y - 12)
Now, swap x and y:
f ⁻¹ (x) = y = 1/3 (e^x - 12)
Secondly and finally, substitute 3 into this eq'n:
f ⁻¹ (3) = 1/3 (e³ -12) = 2.695.....
so 2.695 (to 4 sig.figs/ 3 d.ps)
or if asked for an exact answer then it is just: 1/3 (e³ -12), which can be simplfied to 1/3e³ - 4.
Answer:
23/12 (1 11/12)
Step-by-step explanation:
2 3/4 = 11/4 and in order to do 11/4 minus 5/6, you would have to find the LCM (Least Common Multiple). The LCM is 12. 11/4 times 3 is 33/12 and 5/6 times 2 is 10/12. 33/12 minus 10/12 is 23/12. In a mixed fraction, this would be 1 11/12.
