Answer:
Step-by-step explanation:
2×1000 + (2+2)×100 + (2+2+2)×10 + (2+2+2+2) = 2468
Answer:
well I'm sure if this is entirely correct but i would say it would be 12
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
The answer is vertex is (5/2, 27/2).
Find x= -b/2a where a=-2, b=10 then plug x value back into function to solve for y value of vertex (x,y).
