C4.27. Element pl-image-capture: Capture image from webcam or mobile device

This question demonstrates the image capture element, which enables students to submit images to questions using their local camera or an external device (e.g. a phone or tablet).

If you plan to use AI grading, do not wrap pl-image-capture within another PrairieLearn element, such as pl-card.

Consider the function $f(x) = arcsin(2x) + cos(4x^3-5x)+e^{x^3}$. Find $f'(x)$ and show your work.

Make sure your photo is clear, well-lit, and shows all your work legibly.
Later, you can crop or rotate the image as needed.

Captured image

If necessary, mobile capture can be disabled.

Sketch the bounded region enclosed by the curves $y=-x^2+3$ and $y=2x^2$.

Captured image

If allow-blank is set, students can submit without capturing an image. This is useful when providing multiple image capture elements where not all are required.

Use this space for additional work (optional).
