Front

When is the function increasing? -2.5 < x < 2.5

Back

The function is increasing in the interval -2.5 < x < 2.5.

Front

What is the definition of an odd function?

Back

A function f(x) is odd if f(-x) = -f(x) for all x in the domain.

Front

What is the definition of an even function?

Back

A function f(x) is even if f(-x) = f(x) for all x in the domain.

Front

What is the formula for the nth term of an arithmetic sequence?

Back

a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

Front

What is the solution to the inequality |x - 3| < 5?

Back

-2 < x < 8

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points x1 and x2 in the interval, if x1 < x2 then f(x1) < f(x2).

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has the form f(x) = mx + b, while a quadratic function has the form f(x) = ax^2 + bx + c.
