Which facts are true for the graph of the function below? check all that apply. f(x) = 3 * 4^x a. the range of f(x) is y > 4. b. it is decreasing. c. it is increasing. d. the y-intercept is (0, 4). e. the y-intercept is (0, 3). f. the domain of f(x) is all real numbers.

The choices that are TRUE are ...

C.It is increasing.

E.The y-intercept is (0, 3).

F.The domain of F(x) is all real numbers.

Here is why the other choices are FALSE.

A. The range is y > 0, not y > 4.

B. The multiplier (3) is positive, as is the sign of the exponent. These mean the function will be increasing as x gets larger.

D. 3*4^0 = 3*1 = 3, so the y-intercept is not 4, it is 3.
