Question

Identify the following function's graph by first solving for its x-intercepts and then matching it with the given graphs.

y = 2x² -8x +9

Accepted Answer

No x-intercepts as it does not touch or intersect the x-axis.

Graph of y = 2x² - 8x + 9 with vertex at (0, 9) and no x-intercepts.

Answer

x-intercepts (4 -√7), (4 +√7)

Graph of y = 2x² - 8x + 9 showing vertex at (0, 9) and no x-intercepts.

Answer

x-intercepts (4 -√34)/2, (4 +√34)/2

Graph of y = 2x² - 8x + 9 with vertex at (0, -9) and no x-intercepts.

Answer

x-intercepts -1, 9

Graph of y = 2x² - 8x + 9 with vertex at (0, -9) and no x-intercepts.

Identify the following function's graph by first solving for its x-intercepts and then matching it with the given graphs. y = 2x2 -8x +9
