Answer:

B)
f(2)=5

Explanation:

1. Write the function given:


f(x)=2x+1

2. Find f(2) means to evaluate the function when x=2, so you need to replace x with the number 2, that is:

Replacing x with the number 2:


f(2)=2*(2)+1

Multypling numbers:


f(2)=4+1

Adding the numbers:


f(2)=5

Therefore the answer is B) 5
