We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
To find the unit price, divide the unit by the the total amount:
2.97/4
0.7425
Round this to the nearest cent:
$0.74
Hope this helps!
It is always increasing.
To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. If our first derivative is positive, our original function is increasing and if g'(x) is negative, g(x) is decreasing.
The third one and the fourth one are correct

Let x be the number of employees in 2011. The number of employees in 2012 was 105% of x, i.e.
The number of employees in 2013 was 105% of the number of employees in 2012, i.e.
Since 11025/10000 = 110.25%, there was an increment of 10.25%
