Estimate the range of f(x) by evaluating it across its domain and reporting observed min/max.
This calculator estimates the range (set of output values) of f(x) by evaluating it at 5001 sample points across the specified domain. It reports the observed minimum and maximum values and where they occur. Note: the true range may extend beyond these bounds if the function is unbounded.
Range estimation
Range ≈ [min f(x), max f(x)] for x in [lo, hi]
No — it is a numerical estimate. Extreme values between sample points may be missed, and truly unbounded functions cannot be fully characterized.
Points where the function is undefined are skipped. The range only reflects finite output values found during sampling.
