Which of these statements is true for f(x) = 3 • (9)*?O A. The y-intercept is (0,3).O B. The y-intercept is (0,1).C. The domain of f(x) is x > 0.D. It is always decreasing.

Respuesta :

The given function is

[tex]f(x)=3(9)^x[/tex]

y-intercept means value of y at x = 0, let us put x = 0 and find the value of y

[tex]\begin{gathered} f(x)=3(9)^0 \\ f(x)=3(1) \\ f(x)=3 \end{gathered}[/tex]

The y-intercept is (0, 3)

The answer is A
