Algebra 2 Review Part 1

Front

What is the axis of symmetry for a parabola with vertex at (-3, 2)?

Back

x = -3

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1)

Front

What is the maximum/minimum point of a parabola called?

Back

Vertex

Front

When is a parabola considered to be upside-down?

Back

When the coefficient 'a' is negative.

Front

What is the standard form of a quadratic function?

Back

f(x) = ax^2 + bx + c

Front

How can you determine if a quadratic function opens upwards or downwards?

Back

If 'a' > 0, it opens upwards; if 'a' < 0, it opens downwards.

Front

What does the vertex of a parabola represent?

Back

The highest or lowest point of the parabola.

Front

What is the formula to find the vertex of a parabola in standard form?

Back

Vertex = (-b/(2a), f(-b/(2a)))

Front

What is the effect of changing the value of 'h' in the vertex form of a parabola, y = a(x-h)^2 + k?

Back

It shifts the parabola horizontally.

Front

What is the effect of changing the value of 'k' in the vertex form of a parabola, y = a(x-h)^2 + k?

Back

It shifts the parabola vertically.
