We are given function f(x) = 3x+9.

We need to find the range of the given function.

We are given options

A) y < 9

B) y > 9

C) y > 3

D) y

From the given options we can think that x is in the exponent of 3.

So, the given function is actually f(x) = 3^x +9

Now, we need to find the range of given function.

We can see that first term is and exponential term 3^x and second term is 9.

We know that 3^x will always be greater than 0.

Therefore, 3^x +9 would always be greater than 9.

Therefore, range would be y>9.

So, the correct option is B) y .
