Homework #2: Exponential vs Linear Equations

Which of the following equations represents a linear function?

What is the general form of an exponential equation?

Which characteristic is true for exponential functions but not for linear functions?

• Constant rate of change

• Graph is a straight line

• Growth or decay factor

• Slope-intercept form

If a function has a constant rate of change, it is most likely:

• Exponential

• Linear

• Quadratic

• Logarithmic

Which of the following graphs represents an exponential growth?

• A straight line with a positive slope

• A curve that increases rapidly

• A parabola opening upwards

• A horizontal line

• 4

• 7

• 0

• 1

Which of the following is a characteristic of a linear equation?

• The graph is a curve

• The graph is a straight line

• The graph has a vertex

• The graph is a circle

• The base

• The exponent

• The initial value

• The growth factor

Which of the following equations represents exponential decay?

• -2

• 6

• 0

• -6
