Answer:
In this problem, we are given the following functions:
and its inverse function:
First of all, we want to calculate 
. This can be obtained by substituting
x = 2
into f(x). Doing so, we find:
Then we want to calculate 
. We can do it by substituting
x = 1
into 
. Doing so,
Then we want to calculate 
, which can be found by calculating f(2) and then using it as input for 
We know that
f(2) = 1
Therefore,
Then we want to calculate 
, which can be calculated by plugging
x = -2
into . Doing so,
Then we want to calculate 
; by substituting
x = 4
into f(x), we find
Finally, we want to find 
We know already that
So we have:
First, do 110-30 (You'll get 90). Then, divide 90 by 2 (You'll have 45). Finally, take 45 from 350. Your final answer should be 305.
That's simple!!!
-12/19 = b/19
as denominators are same, you can cancel that.
b = -12
It’s b i got that same question and got it right
5x^2+3x-4=0
<span>x^2+3x/5-4/5=0 </span>
<span>x^2+3x/5=4/5 </span>
<span>x^2+3x/5+9/100=89/100 </span>
<span>(x+3/10)^2=89/100 </span>
<span>x+3/10=±(√89)/10 </span>
<span>x=-3/10±√89/100 </span>
<span>x=-3±(√89/10)</span>
