Find the illegal values of c in the multiplication statement c^2-3c-10/c^2+5c-14 times c^2-c-2/c^2-2c-15

Citrus2011 [14]

Answer: c ≠ {-7, -3, 2, 5}

Step-by-step explanation:

$\frac{c^{2} - 3c - 10}{c^{2} + 5c - 14} * \frac{c^{2} - c - 2}{c^{2} - 2c - 15}$

= $\frac{(c - 5)(c + 2)}{(c + 7)(c - 2)} * \frac{(c - 2)(c + 1)}{(c - 5)(c +3)}$

restrictions:

c + 7 ≠ 0 c - 2 ≠ 0 c - 5 ≠ 0 c + 3 ≠ 0

c ≠ -7 c ≠ 2 c ≠ 5 c ≠ -3

When working with scatterplots and the dots line up on a graph, but more in a curvy line, this would be an example of which mode

Karo-lina-s [1.5K]

The best answer to this question is quadratic. The model that can be seen in a scatterplot wherein the dots line up on a graph in a curvy manner would be the quadratic model.

Additional info: If the dots are forming a straight lne, it's linear. If it shoots up, then it's an exponential one.
