Find a formula for a function that has vertical asymptotes x = 2 and x = 7 and horizontal asymptote y = 2.

Pie

Hello :

hello : 
1 ) if : xـــــــ> ± ∞ 
limf(x) = b ....(b∈R) so : y=b is the equation of the line horizontal asymptote.

2) if : xـــــــ> a ...(a∈R)
limf(x) = ± ∞
so : x=a is the equation of the line vertical asymptote.

hint : in this exercice : a = 2 or a = 7 but : b=2

Find the solutions of the quadratic equation 14x^2+9x+10=014x

Vesnalui [34]

Answer:

Option B. $x=-\frac{9}{28}(+/-)\frac{\sqrt{479}}{28}i$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$14x^{2}+9x+10=0$

$a=14\\b=9\\c=10$

substitute in the formula

$x=\frac{-9(+/-)\sqrt{9^{2}-4(14)(10)}} {2(14)}$

$x=\frac{-9(+/-)\sqrt{-479}} {28}$

Remember that

$i=\sqrt{-1}$

substitute

$x=\frac{-9(+/-)\sqrt{479}i} {28}$

$x=-\frac{9}{28}(+/-)\frac{\sqrt{479}}{28}i$
