Where ever u see a y change it to an x
3x+2(x)=20
5x=20
x=4
Answer:
x = 2
Step-by-step explanation:
x = 2 represents the entire vertical line of positive 2 on the x-axis. That is where the shape of the function becomes symmetrical.
The answer is B because y=mx+b and -2 is m so y=-2+1
Hello :
hello : <span>
1 ) if : x</span>ـــــــ> ± ∞
<span>
limf(x) = b ....(b</span>∈R) so : y=b is the equation of
the line horizontal asymptote.
<span>
2) if : x</span>ـــــــ>
a ...(a∈R)<span>
limf(x) = ± ∞
<span>so : x=a is the equation of the
line vertical asymptote.</span></span>
<span><span>hint : in this exercice : a = 2 or a = 7 but : b=2</span></span>
