ALG 1 PT MIX (Part 2)

Front

What is the factored form of the equation 0 = x² - 4x + 4?

Back

(x - 2)(x - 2) or (x + -2)(x + -2)

Front

What does it mean if a quadratic function has a maximum value?

Back

The parabola opens downwards and the vertex is the highest point.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

If f(x) = 3x - 9, what is f(5)?

Back

f(5) = 6.

Front

What does the equation f(x) = x² represent?

Back

A parabola that opens upwards.

Front

How do you find the zeros of a quadratic equation?

Back

By factoring, using the quadratic formula, or completing the square.

Front

What is the vertex of a parabola in the form y = ax² + bx + c?

Back

The vertex can be found using the formula (-b/(2a), f(-b/(2a))).

Front

What is the significance of the 'a' value in the quadratic equation y = ax² + bx + c?

Back

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

Front

What is the definition of slope in a linear equation?

Back

The slope (m) is the ratio of the rise (change in y) to the run (change in x).

Front

What does it mean for a function to be increasing?

Back

The output values of the function increase as the input values increase.
