Comparing Functions in Algebra 1

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

• y = mx + b

• y = ax^2 + bx + c

• y = a * b^x

• y = x^2 + bx + c

In the equation y = mx + b, what does 'm' represent?

• The slope

• The x-intercept

• The y-intercept

• The constant term

What is the standard form of a quadratic equation?

• y = x^2 + bx + c

• y = ax^2 + bx + c

• y = a * b^x

• y = mx + b

In a quadratic equation, what does the 'a' value determine?

• The y-intercept

• The direction the parabola opens

• The x-intercept

• The vertex

What is the standard form of an exponential function?

• y = x^2 + bx + c

• y = a * b^x

• y = mx + b

• y = ax^2 + bx + c

In the exponential function y = a * b^x, what does 'a' represent?

• The exponent

• The common multiple

• The initial value

• The slope

What is the average rate of change?

• The x-intercept of a function

• The slope between two points on a non-linear function

• The y-intercept of a function

• The slope between two points on a linear function

How do you calculate the average rate of change?

• Difference of x and y values

• Change in x over change in y

• Change in y over change in x

• Sum of x and y values

What is the average rate of change between the points (1, -4) and (4, 5) on a quadratic function?

• 3

• 1

• 2

• 4

What is the main topic covered in sections 9.4 and 9.5?
