Answer:

Step-by-step explanation:

(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)

= 3 + 6 + 9 + 12 + 15

= 45

How is the graph of y = -8x2 - 2 different from the graph of y = -8x2?

Aleks04 [339]

Answer:

(Answer D)

Step-by-step explanation:

Please use " ^ " to indicate exponentiation: y = -8x^2 - 2, y = -8x^2

The graph of y = -8x^2 is an inverted parabola with vertex at (0, 0).

That of y = -8x^2 - 2 is the same as above, except that the whole graph has been shifted 2 units down (Answer D).
