Comparing Linear Quadratic Exponential Characteristics

Identify the type of function: f(x) = 3x + 2

• Exponential function

• Quadratic function

• Linear function

• Logarithmic function

What are the key characteristics of an exponential function?

• The key characteristics of an exponential function are that it grows at an increasing rate and never crosses the x-axis.

• The key characteristics of an exponential function are that it shrinks at an increasing rate and never crosses the x-axis.

• The key characteristics of an exponential function are that it grows at a constant rate and never crosses the x-axis.

• The key characteristics of an exponential function are that it grows at a decreasing rate and always crosses the x-axis.

Identify the type of function: h(x) = 2^x

• Quadratic function

• Logarithmic function

• Exponential function

• Linear function

Analyze the rate of change in the function: y(x) = -2x^2 + 4x - 1

• y'(x) = -4x + 4

• y'(x) = -2x^2 + 4x - 1

• y'(x) = -2x^2 - 4x - 1

• y'(x) = -4x - 4
