Front

What is the domain of a graph?

Back

The domain of a graph is the set of all possible x-values (inputs) for which the function is defined.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on its orientation.

Front

What is the equation for the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, given by the equation x = h, where (h,k) is the vertex.

Front

How do you find the number of cells after h hours if a cell doubles every hour?

Back

Use the exponential function n = n0(2^h), where n0 is the initial number of cells.

Front

What is an exponential expression?

Back

An exponential expression is a mathematical expression in the form of a^x, where 'a' is a constant and 'x' is a variable.

Front

How do you simplify the expression 2^3 * 2^4?

Back

Use the property of exponents: a^m * a^n = a^(m+n). So, 2^3 * 2^4 = 2^(3+4) = 2^7.

Front

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

Back

A linear function has a constant rate of change and is represented by a straight line, while a quadratic function has a variable rate of change and is represented by a parabola.

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the x-values increase, the y-values also increase.

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).
