Problem 36 of 7
Compare quadratics f(x) = (x+2)^2 - 3 and g(x) = 2x^2 + x + 1 by y-intercept.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Find each quadratic's value at x=0.
2. Compare the y-intercept values.
3. State which is higher, lower, or equal.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Comparing zeros or vertices when y-intercept is requested.
