Exam Overview
Precalculus, 10th Edition by Ron Larson is a comprehensive textbook designed to prepare
students for calculus. Known for sound, consistently structured explanations of
mathematical concepts and exercises, the Tenth Edition continues to revolutionize the way
students learn by incorporating more real-world applications and innovative technology.
"How Do You See It?" exercises let students practice applying concepts, and "Summarize"
features and "Checkpoint" problems reinforce understanding of the skills needed to prepare
for tests.

functions, graphs of other trigonometric functions, inverse trigonometric functions,
applications and models
- Analytic Trigonometry: Using fundamental identities, verifying trigonometric identities,
solving trigonometric equations, sum and difference formulas, multiple-angle and product-
to-sum formulas
,- Additional Topics in Trigonometry: Law of Sines, Law of Cosines, vectors in the plane,
vectors and dot products, the complex plane, trigonometric form of a complex number

Chapter 1: Functions and Their Graphs
(55 Questions)
Question 1
What is the domain of the function \( f(x) = \sqrt{x - 3} \)?
A) \( (-\infty, 3] \)
B) \( [3, \infty) \)
C) \( (-\infty, 3) \)
D) \( (3, \infty) \)
, Correct Answer: B) \( [3, \infty) \)
Rationale: The radicand must be non-negative, so \( x - 3 \geq 0 \), which gives \( x \geq 3 \).
The domain is \( [3, \infty) \).
---
Question 2
If \( f(x) = 2x^2 - 3x + 1 \), find \( f(-2) \).
A) 15
B) 3
C) -1
D) 11
Correct Answer: A) 15
Rationale: Substitute \( x = -2 \): \( f(-2) = 2(-2)^2 - 3(-2) + 1 = 2(4) + 6 + 1 = 8 + 6 + 1 = 15 \).
---
Question 3
Which of the following represents a function?
A) \( x = y^2 \)
B) \( y^2 = x^2 + 1 \)
C) \( x^2 + y^2 = 9 \)
D) \( y = 3x + 2 \)
