Q:
# Which of the following graphs is described by the function given below?y = 2x^2 + 8x +3

Accepted Solution

A:

Answer:AStep-by-step explanation:y = 2x² + 8x + 3Complete the square:y = 2(x² + 4x) + 3y = 2(x² + 4x + 4) + 3 - 2(4)y = 2(x + 2)² - 5So the vertex is at (-2, -5). The graph must be Graph A.
