| Domain | Sample Question Types | | :--- | :--- | | | Linear equations, systems of equations (with infinite or no solutions), linear inequalities, word problems | | Advanced Math | Quadratic functions, discriminant analysis, factoring complex expressions, interpreting graphs of higher-order polynomials, exponential functions | | Problem-Solving & Data Analysis | Ratios, percentages, probability, data from tables and charts, scatterplots, proportional relationships | | Geometry & Trigonometry | Area and volume, circle equations, lines, angles, right triangles, basic trig (sine, cosine, tangent) |
). For exactly one real solution, the discriminant must equal zero:
: The given equation is already in vertex form, where is the vertex. Substitute the Vertex : Plug into the equation.
The function (f(x) = ax^3 + bx^2 + cx + d) has a point of inflection at (x = 2) and a relative maximum at (x = -1). If (f(0) = 5), what is (f(4))?
