Step-by-step explanation:
2x^2 + x - 28
= 2x^2 - 8x + 7x - 28
= 2x(x-4) +7(x-4)
= (2x+7)(x-4)
2x+7 = 0 or x-4 = 0
x = -7/4 or x = 4
Answer:
Step-by-step explanation:
Domain: ℝ
Range: [-3, ∞)
When x<4, the graph is decreasing.
When x>4, the graph is increasing.
Vertex (4, -3)
Answer:
x = 8
Step-by-step explanation:
Triangle OBC is congruent to triangle OBA (SAS ---- side angle side)
the anser to that problem is -1/3
