Answer:
The true facts for the function are A, C and E.
Step-by-step explanation:
We are given the function, [tex]f(x)=(\frac{2}{5})^x[/tex]
From the graph below, we see that,
Domain of the function is the set of all real numbers.
Range of the function is the set [tex]\{y| y>0\}[/tex].
Y-intercept is the point when graph crosses the y-axis. So, we see that at (0,1), the graph of the function cuts the y-axis.
So, the y-intercept is (0,1).
Moreover, as the values of x are increasing, the values of f(x) are decreasing.
Thus, the function is a decreasing function.
Hence, the true facts for the function are A, C and E.
