Mixed Practice A

Practice a balanced mix of notation, domain, range, key features, and comparisons.

This set blends quick function checks with feature interpretation from equations, graphs, tables, and contexts.

How to use this set

Move one question at a time. Decide whether you are evaluating, identifying a feature, or comparing two functions.

Question 5

Quadratic minimum

The function g(x)=(x+1)^2-6 opens upward. What is its minimum value?

Question 6

Exponential model

A table has outputs 5,15,45,135 for equal input steps. Which type of function best matches the pattern?

Question 7

Compare intercepts
