In the quadratic function f(x) = ax² + bx + c, what does 'a' control?

• The value of 'a' determines whether the graph opens up or down.

• The value of 'a' affects the width of the parabola.

• The value of 'a' determines the y-intercept of the graph.

• The value of 'a' controls the position of the vertex.

What does it mean for two lines to be perpendicular?

• Two lines are perpendicular if the product of their slopes is -1.
