Calculation steps

  1. 1Expression: y = x^2 — implicit multiplication expanded (2x→2*x), then each x is substituted
  2. 2Sample 481 evenly spaced points on [-5, 5]
  3. 3y range in view: [0, 25]
  4. 4y-intercept: f(0) = 0
  5. 51 zero(s) found: x ≈ -1.0e-6 (sign change + bisection)

Sample points

x=-5 → 25
x=-3.75 → 14.063
x=-2.5 → 6.25
x=-1.25 → 1.563
x=0 → 0
x=1.25 → 1.563
x=2.5 → 6.25
x=3.75 → 14.063
x=5 → 25
Tips: sqrt/ln require positive inputs (out-of-domain points are skipped automatically); 1/x and tan(x) break at vertical asymptotes by design; remember to switch DEG/RAD for trig functions; even functions are symmetric about the y-axis and odd functions about the origin — check visually on the graph.
