Math Teaching Whiteboard With Handwritten Formulas And Function Graphs

Photorealistic 16:9 horizontal educational whiteboard scene, 2K+ high resolution, soft even ambient lighting with no harsh glare obscuring content. The whiteboard takes up 85% of the frame, with a pale light green surface that has faint eraser smudges and subtle usage marks to look like a real regularly used classroom board. In the top left corner, neatly handwritten in smooth dark blue dry-erase marker with medium readable font size is the quadratic function formula: f(x) = ax² + bx + c. Below the formula is a mathematically accurate corresponding coordinate graph: thin black x and y axes with clearly labeled directional arrows, evenly spaced tick marks and numerical labels on both axes, a slightly thicker smooth bright blue parabola curve plotted correctly, key points including the vertex, x-intercepts, and y-intercept are marked with small white dots and paired with clear correct coordinate labels. At the bottom right edge of the whiteboard rest 3 dry-erase markers (black, red, blue) and a standard whiteboard eraser to add authentic classroom context. All mathematical content is fully accurate with no errors, the overall scene is clean and professional, suitable for use as teaching material or knowledge content illustration.
