Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula and any 2 ordered pairs from the table.
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 8) and (x₂, y₂ ) = (- 1, 4) ← 2 points from the table
m = =
= - 4
This downward-opening parabola has its vertex at x = -8, so the function is decreasing on the interval (-8, ∞).
