Answer:

$\boxed{7-26i}$

Step-by-step explanation:

The binomials are multiplied in the usual way, using FOIL or the distributive property:

(5 -2i)(3 -4i) = 15 -20i -6i +8i²

Since i² = -1, this becomes ...

= 15 -20i -6i -8 = 7 -26i

Option C: -3 is the average rate of change between $x=-1$ and $x=1$

Explanation:

The formula to determine the average rate of change is given by

Average rate of change = $\frac{y_2-y_1}{x_2-x_1}$

We need to find the average rate of change between $x=-1$ and $x=1$

Thus, from the table, we have,

$x_1=-1$ , $y_1=5$

$x_2=1$ , $y_2=-1$

Thus, substituting these values in the formula, we get,

Average rate of change = $\frac{-1-5}{1+1}$

$=\frac{-6}{2}$

$=-3$

Thus, the average rate of change between $x=-1$ and $x=1$ is -3.

Hence, Option C is the correct answer.
