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 O. Therefore, 3^x +9 would always be greater than 9. Therefore, range would be y>9. So, the correct option is B) (y | y > 9}.
