Given that f(2)=9 we know that f(x) can be (insert part one of answer) choices f(x)=2x+5 or f(x)=4x+5.

This means that f(3) is
choices 11 or 17(insert part 2 of answer)

f(x) = 2x+5

f(3) = 2(3) +5 = 6+5 =11

There fore f(3) =11

The first function is correct

Step-by-step explanation:

Given f(2) =9 and given functions are f(x) = 2x+5 and f(x) =4x+5

The fsecond function is not satisfies f(2)=9 because

f(x) = 4x+5

f(2) = 4(2)+5 = 13≠9

f(x) = 2x+5

f(2) = 2(2)+5=9

therefore first function is satifies

f(x) = 2x+5

f(3) = 2(3) +5 = 6+5 =11

There fore f(3) =11

the infinity sign
