AGS 2 - Unit 2 Test Day Practice

Front

What is the factored form of the quadratic function f(x) = -x^2 - 4x?

Back

f(x) = -x(x + 4)

Front

Factor completely: 2x^2 + 22x + 60

Back

2(x + 5)(x + 6)

Front

What are the x-intercepts of the function f(x) = (x - 2)(x + 3)?

Back

(2,0) and (-3,0)

Front

Factor completely: y = x^2 - 2x - 24

Back

(x + 4)(x - 6)

Front

What is the standard form of a quadratic function?

Back

f(x) = ax^2 + bx + c, where a, b, and c are constants.

Front

What does it mean for a quadratic function to be in factored form?

Back

It means the function is expressed as f(x) = a(x - r1)(x - r2), where r1 and r2 are the roots.

Front

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

Back

Set f(x) = 0 and solve for x.

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x - h)^2 + k, where (h, k) is the vertex.

Front

What is the significance of the 'a' value in a quadratic function?

Back

It determines the direction of the parabola (upward if a > 0, downward if a < 0) and affects the width.

Front

What is the quadratic formula?

Back

x = (-b ± √(b^2 - 4ac)) / (2a) for the equation ax^2 + bx + c = 0.
