Graphing conic sections helps visualize their properties and prepares students for advanced calculus topics involving parametric equations and polar coordinates.
2.4 Polynomial and Rational Functions
Polynomial and rational functions are central to pre-calculus‚ building on algebraic concepts. Polynomials are expressions of the form P(x) = a_nx^n + … + a_1x + a_0‚ where n is the degree. They are classified as linear‚ quadratic‚ cubic‚ or higher‚ each with distinct graph shapes. Rational functions involve ratios of polynomials‚ such as f(x) = P(x)/Q(x)‚ and are analyzed for asymptotes‚ holes‚ and intercepts. Understanding these functions is crucial for solving equations‚ modeling real-world phenomena‚ and transitioning to calculus. Polynomial functions are continuous and smooth‚ while rational functions can have discontinuities. Both are essential for advanced problem-solving in mathematics and science.
2.5 Exponential and Logarithmic Functions
Exponential and logarithmic functions are fundamental in pre-calculus‚ essential for modeling growth‚ decay‚ and inverses. Exponential functions follow the form y = ab^x‚ where a and b are constants‚ with b > 0 and b ≠ 1. When b > 1‚ the function grows rapidly‚ and when 0 < b < 1‚ it decays. Logarithmic functions‚ the inverse of exponentials‚ are represented as y = log_b(x)‚ answering: "To what power must b be raised to obtain x?" Key properties include log_b(xy) = log_b(x) + log_b(y) and log_b(x^n) = n log_b(x)‚ aiding in simplifying expressions and solving equations.
Graphing these functions reveals distinct behaviors: exponentials have horizontal asymptotes‚ while logarithmics have vertical asymptotes. Solving exponential and logarithmic equations often involves taking logarithms of both sides. Real-world applications include population growth and sound measurement‚ showcasing their versatility and importance in various fields.
