• The graph of f(x) always exceeds the graph of g(x) over the interval [0, 5].

• The graph of g(x) always exceeds the graph of f(x) over the interval [0, 5].

• The graph of g(x) exceeds the graph of f(x) over the interval [0, 4], the graphs intersect at a point between 4 and 5, and then the graph of f(x) exceeds the graph of g(x).

• The graph of f(x) exceeds the graph of g(x) over the interval [0, 4], the graphs intersect at a point between 4 and 5, and then the graph of g(x) exceeds the graph of f(x).

Which statement is true about the graphs of exponential functions?

• The graphs of exponential functions never exceed the graphs of linear and quadratic functions.

• The graphs of exponential functions always exceed the graphs of linear and quadratic functions

• The graphs of exponential functions eventually exceed the graphs of linear and quadratic functions

• The graphs of exponential functions eventually exceed the graphs of linear functions but not quadratic functions.

• The values of f(x) will always exceed the values of g(x).

• The values of g(x) will always exceed the values of f(x).

• The values of f(x) exceed the values of g(x) over the interval [0, 5].

• The values of g(x) begin to exceed the values of f(x) within the interval [4, 5].

CCSS.HSF.LE.A.2

 $f\left(x\right)=75\left(2\right)^x$  

Consider this function for cell duplication. The cells duplicate every minute.

• The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.

• The 75 is the initial number of cells, and the 2 indicates that the number of cells increases by 2 every minute.

• The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells doubles every minute.

• The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells increases by 2 every minute.
