Answer:

X is an input value, or independent variable

Step-by-step explanation:

12. The x represents the input values for the equation.

To get our output f(x) also known as y, we need the x, so x is also known as the independent variable and y as the dependent variable.

NEED HELP ASAP! 25 POINTS! Find the equation, in vertex form, for a parabola with a vertex of (2,-5) that goes through the point

Gre4nikov [31]

Standard form of the parabola function: (y-k) = a(x-h)²

vertex (h,k)==> vertex (2,-5) [given]. Now plug==> y+5 =a(x-2)²

To calculate a, plug in the equation the coordinates of A(3,4)

4+5 = a(3-2)² ==> 9=a

Finally the equation is f(x) = y+5 = 9(x-2) or y = 9(x-2)² -5

Or f(x) =y = 9x² - 36x + 3

Answer:

The sequence converges to infinity.

Step-by-step explanation:

$a_n = \frac{n^3 - n}{n^2 + 5n}\\\\ \lim_{n \to \infty} a_n = \lim_{n \to \infty} \frac{n^3 - n}{n^2 + 5n}$

$= \lim_{n \to \infty} \frac{n(n^2 - 1)}{n(n + 5)} \\\\= \lim_{n \to \infty} \frac{(n^2 - 1)}{(n + 5)}\\\\= \lim_{n \to \infty} \frac{n(n - \frac{1}{n})}{n(1 + \frac{5}{n})}\\\\= \lim_{n \to \infty} \frac{(n - \frac{1}{n})}{(1 + \frac{5}{n})}$

$denominator = \lim_{n \to \infty} 1 + \frac{5}{n} = 1 + \lim_{n \to \infty} \frac{5}{n} = 1+0 = 1$

$numerator = \lim_{n \to \infty} n - \frac{1}{n} = \infty$

Therefore,

$\lim_{n \to \infty} a_n = \frac{ \infty}{1} = \infty$
