likoan [24]

In order to construct a scatter plot, the essential items include;

A: The variable measured on the vertical axis. This is because the variables on both axes is the major reason why the graph is being constructed, so the variable must be identified.

B: The variable measured on the horizontal axis, for the same reason as stated above.

D: The scale of vertical and horizontal axes. This helps to read off the range of the data set without going beyond the limit

V(x)=x^2-25

Whitepunk [10]

Answer:

-∞ < x < -5 ∪ -5 < x < -3/2 ∪ -3/2 < x < ∞

Step-by-step explanation:

The domain of any polynomial is "all real numbers." The domain of any rational function excludes any values of the variable that result in the denominator being 0. The function is "undefined" there.

$v(x)=\dfrac{x^2-25}{2x^2+13x+15}=\dfrac{(x+5)(x-5)}{(x+5)(2x+3)}\qquad x\notin \{-5,-\dfrac{3}{2}\}$

The values x=-5 and x=-3/2 make the denominator of v(x) become 0, so those values are excluded from the domain of v(x). The function is "undefined" when its denominator is zero.

-∞ < x < -5 ∪ -5 < x < -3/2 ∪ -3/2 < x < ∞

_____

<em>Additional comment</em>

The numerator and denominator factors (x+5) cancel each other, so there is no vertical asymptote at x=-5. Rather, the function has a "hole" there, where it is undefined. The limit as the function approaches x=-5 from either direction is v(x) = 10/7.
