How do you find the end behavior?
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

In this lesson, you will learn what the "end behavior" of a polynomial is and how to analyze it from a graph or from a polynomial equation.

What's "end behavior"?

The end behavior of a function

f

ff describes the behavior of the graph of the function at the "ends" of the

x

xx-axis.

In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the

x

xx-axis (as

x

xx approaches

+

∞

+∞plus, infinity) and to the left end of the

x

xx-axis (as

x

xx approaches

−

∞

−∞minus, infinity).

yyxxy=

f(x)

y=f(x)

x gets

x gets

more

+ more +

f(x) gets

f(x) gets

more

+ more +

For example, consider this graph of the polynomial function

fff. Notice that as you move to the right on the x

xx-axis, the graph of f

ff goes up. This means, as x

xx gets larger and larger,

f(x)

f(x)f, left parenthesis, x, right parenthesis gets larger and larger as well. Mathematically, we write: as

x→+x→+∞x, right arrow, plus, infinity,

f(x)→+∞

f(x)→+∞f, left parenthesis, x, right parenthesis, right arrow, plus, infinity. (Say, "as xxx approaches positive infinity, f(x)

f(x)f, left parenthesis, x, right parenthesis approaches p

The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
Irina-Kira [14]

9514 1404 393

Answer:

  q = 40

Step-by-step explanation:

When the quadratic has roots p and r, it can be factored as ...

  (x -p)(x -r) = x² -(p+r)x +pr

So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...

  p + r = 14

  p - r = 6

  2p = 20 . . . add the two equations

  p = 10

  r = 14 -p = 4

The value of interest is then ...

  q = pr = (10)(4)

  q = 40

__

The graph shows the roots to be 4 and 10, as we found.
