Front

What is the factored form of the expression 3x^2 + 33x + 30?

Back

3(x+10)(x+1)

Front

What are the coordinates of the point where the line intersects the x-axis and y-axis for the equation y = 2x - 4?

Back

(2, -2)

Front

What are the x-intercepts and y-intercepts of the function f(x) = 2x^2 - 12x + 24?

Back

(0, 4) and (6, 0)

Front

What is the value of the function f(x) = 4x^2 when x = 2?

Back

f(2) = 32

Front

What is the factored form of the polynomial 4y^4 - 28y^3 + 48y^2?

Back

4y^3(4y - 7)

Front

What is the definition of an x-intercept?

Back

An x-intercept is a point where the graph of a function crosses the x-axis, meaning the output (y-value) is zero.

Front

What is the definition of a y-intercept?

Back

A y-intercept is a point where the graph of a function crosses the y-axis, meaning the input (x-value) is zero.

Front

How do you find the x-intercepts of a quadratic function?

Back

Set the function equal to zero and solve for x.

Front

What is the vertex form of a quadratic function?

Back

The vertex form is given by f(x) = a(x-h)^2 + k, where (h, k) is the vertex of the parabola.

Front

What is the quadratic formula used for?

Back

The quadratic formula is used to find the solutions (roots) of a quadratic equation in the form ax^2 + bx + c = 0.
