Alg B 7.6 and 7.7 Linear vs. Exponential Equations Assessment

Which type of equation represents the function y = 2x + 3?

• Linear equation

• Exponential equation

• Quadratic equation

• Logarithmic equation

• Linear relationship

• Exponential relationship

• Quadratic relationship

• Inverse relationship

Which equation shows a constant rate of change?

• y = -5x + 2

The equation y = -3x + 7 is:

• Exponential because of the negative number

• Linear because it has a constant rate of change

• Neither linear nor exponential

• Exponential because it contains a variable

What characterizes an exponential equation?

• The variable is always in the base

• The variable is always in the exponent

• The variable is always negative

• The variable is always positive

The equation y = 5(2^x) is:

• Linear because it contains multiplication

• Neither linear nor exponential

• Exponential because the variable is in the exponent

• Linear because it can be graphed

Which equation represents a linear relationship?

• y = 3x + 1

The equation y = 6x - 2 shows:

• Exponential growth

• Linear growth

• Neither linear nor exponential growth

• Both linear and exponential growth

Which equation would create a curved line when graphed?

• y = 2x + 5

• y = -4x + 1

• y = 7x - 3

The equation y = -2(3^x) is:

• Linear because of the negative coefficient

• Exponential despite the negative coefficient

• Neither linear nor exponential

• Linear because it can be simplified
