Comparing Functions

• The function f(x) has a greater y intercept than the function g(x)
• The function g(x) has a greater rate of change than the function f(x)
• The function g(x) has a greater y intercept than the function f(x)
• The rate of change for both g(x) and f(x) are equal 

• The rate of change of f(x) is less than the rate of change of g(x)
• The rate of change of f(x) is greater than the rate of change of g(x) 
• The y intercept of f(x) is equal to the rate of change of g(x) 
• The y intercept of f(x) is greater than the rate of change of g(x)

• r(x) because its rate of change is 4 while the rate of change for s(x) is 2 over the interval [1,3]

• r(x) because its rate of change is 3 while the rate of change for s(x) is 2 over the interval [1,3]

• s(x) because its graph appears steeper than that of r(x) over the interval [1, 3]

• Neither, both graphs appear to rise at the same rate

• The y-intercept of the function f(x) is less than the y-intercept of the function g(x) 
• The y-intercept of the function f(x) is greater than the y-intercept of the function g(x)
• The y-intercept of the function f(x) is equal to the y-intercept of the function g(x)
• The y-intercepts cannot be determined

Is this table linear, quadratic, exponential, or none of the above?

• linear

• quadratic

• exponential

• none of the above

Which type of function is given by the table?

• Linear

• Quadratic

• Exponential

• None of the above

• Linear, because there is a constant rate of change
• Exponential, because there is a common ratio
• Quadratic, because there is a constant rate of change
• Quadratic, because the second difference is constant
