Find the Domain: Rational, Cube Root & Square Root Functions (Stewart Ch.1 Q3)

Three domain problems, three rules. (a) Rational: exclude the zeros of the denominator — (−∞, −2) ∪ (−2, 1) ∪ (1, ∞). (b) Cube root over polynomial: all real numbers, no restrictions. (c) Sum of two square roots: intersect the two radicand conditions — (−∞, −1] ∪ [1, 4]. The reflexes every pre-calc and AP Calc student needs before limits.

Difference Quotient of f(x) = x³ at x = 2 (Stewart Ch.1 Q2)

Expand (2 + h)³ with the binomial expansion, subtract f(2) = 8, cancel the 8s, and divide each term by h. The simplified answer is h² + 6h + 12 — and as h → 0 it becomes f′(2) = 12. The algebraic foundation of every limit definition of the derivative.

Reading a Function from Its Graph: f(−1), f(2), Zeros, Domain & Range (Stewart Ch.1 Q1)

Stewart's Calculus opens with a five-part graph-reading problem that every later chapter assumes you can do without thinking: state f(−1), estimate f(2), solve f(x) = 2, estimate the zeros, and write down the domain and range. Final answers f(−1) = −2, f(2) ≈ 2.8, x = −3 and 1, zeros at x ≈ −2.3 and 0.3, domain [−3, 3], range [−2, 3]. Worked the SOMATH way on the Upper West Side — the function-notation trap, the horizontal-line trick for f(x) = k, and the bracket-versus-parenthesis convention for domain and range.

Coordinate Geometry with Two Points: Line, Midpoint & Circle (Stewart 9e Q4)

Stewart's Calculus 9th Edition diagnostic Question 4 gives you two points — A(−7, 4) and B(5, −12) — and chains together every coordinate-geometry skill before AP Calc: slope, line equation and intercepts, midpoint, distance, perpendicular bisector, and the circle with AB as diameter. Slope −4/3. Midpoint (−1, −4). AB = 20. Perpendicular bisector y = (3/4)x − 13/4. Final circle (x + 1)² + (y + 4)² = 100.

Equation of a Circle from Center and a Point (Stewart Calculus 9e Q2)

Stewart's Calculus 9th Edition diagnostic Question 2 gives you a center — (−1, 4) — and one point on the circle — (3, −2) — and asks for the equation. Two ideas glued together: standard form (x − h)² + (y − k)² = r², and the squared distance formula. Final answer (x + 1)² + (y − 4)² = 52, radius 2√13 ≈ 7.21. Worked the SOMATH way on the Upper West Side — the sign trick, the squared-distance shortcut, and why you should never take a square root and then square it again.

We walk through it the way we teach it at SOMATH on the Upper West Side, with the sign traps, the half-square trick, and the radius vs. r² mistake that costs students the most points.
