Answer:
1
Step-by-step explanation:
We have the function
and we want to know the value of 
.
The first step is to find 
; we can subtract 1 from it at the end! But what does mean?
Basically, we're saying <em>"what is the value of the function when </em>
<em> ?"</em>
So, we simply replace 
with 3 in the function, and we get:
.
Finally, we subtract 1 to find 
.
Step-by-step explanation:
Selling price = Rs.80
Cost price = Rs.100
here, CP > SP
Now...
Loss ( L ) = CP - SP
= RS.100 - 80
= Rs.20
Now...
= 20 %
Exponential growth because maths is good
I hope this helps you
a=4
b=9
c= -1
disctirminant =b^2-4ac
disctirminant =9^2-4.4. (-1)
disctirminant =97
x1=-9+square root of 97/2.4= -9+square root of 97/8
x2= -9-square root of 97/2.4= -9-square root of 97/8
