Question

Which facts are true for the graph of the function below? Check all that apply.

Answer 1

A b d just took the test

Explanation:

Answer 2

`F(x)+\left((2)/(5)\right)^x`

C. The y-intercept is (0, 1)

`f(0)=\left((2)/(5)\right)^0=1\to(0,\ 1)`
D. The range of F(x) is y > 0

`F(x)=\left((2)/(5)\right)^x > 0\ for\ x\in\mathbb{R}`
E. It is decreasing

`f(x)=a^x\\if\ a > 1\ then\ is\ increasing\\if\ a\in(0;\ 1)\ then\ is\ decreasing\\\\F(x)=\left((2)/(5)\right)^x\to a=(2)/(5)\in(0;\ 1)`


A. Not, because the domain is all real numbers
B. Not, because it is decreasing.
F. Not, because the x-intercept is not exist.
