Substitute the values of x to the equation of the function f:

Therefore we have two points (-1, 7) and (2, 1).
We can calculate the slope of line l.
The formula of a slope:

Substitute:

<h3>Answer: A) -2.</h3>
Answer:
20
Step-by-step explanation:
Assuming that the equation is x³ = 64, that can be solved by putting cube root on both sides like so: ∛(x³) = ∛64, which simplifies to <em>x = 4</em>.
Plugging that into our expression gives us <em>4² + 4</em>, which is 20.
