Precalc. AB Semester Final Part 1

Solve the inequality. Use algebra to solve the corresponding equation.

x² - 2x - 3 ≤ 0

Find the range of the function:

f(x) = (x + 3)² + 7

Choose ALL of the following that have a range of [-4, ∞)

Determine the intervals on which the function is increasing, decreasing, and constant.

• Constant

• (-4, 4)

• Increasing

• Decreasing

Match the function with the graph

• 12x² + 9x + 23

• 4x² + 9x + 7

• 4x² + 3x - 3

• 12x² + 9x + 7

• y = 0

• y = 8

• y = -8

• y = 1

• y = -1
