Front

What is the y-intercept of the function f(x) = x^2 - 8x + 15?

Back

The y-intercept is the point (0, 15).

Front

What does the vertex of a parabola represent?

Front

What is the significance of the coefficients in a quadratic function?

Back

The coefficient 'a' determines the direction of the parabola, 'b' affects the position of the vertex, and 'c' is the y-intercept.

Front

How do you convert a quadratic function from standard form to vertex form?

Back

You can complete the square to convert from standard form to vertex form.

Front

What is the formula for the area of a rectangle?

Back

Front

What is the effect of changing the 'a' value in a quadratic function?

Back

Changing 'a' affects the width and direction of the parabola; if 'a' is positive, it opens upwards, and if negative, it opens downwards.
