(x+(x+2)+(x+4)+(x+6))=4x+12=212
x+x+x+x(2+4+6)=4x+12=212
4x (2+4+6)=4x+12=212
4x(6+6)=4x+12=212
12+4x=4x+12=212
<u>-12 -12 -12</u>
4x=4x=200
<u>/4 /4 /4</u>
<u>x=x=50</u>
<u>x=50</u>
The function is decreasing on the interval (- infinity, + infinity).
Answer: 1.02500
Step-by-step explanation:
The equation of the asymptote is 
Explanation:
The given equation is 
We need to determine the horizontal asymptote of the equation.
The given equation is of the exponential function of the form
and has a horizontal asymptote 
Hence, from the above equation, the value of k is 1.
Therefore, we have,

Thus, the horizontal asymptote is 
Therefore, the asymptote of the equation is
