Answer:
B) [tex]f(2)=5[/tex]
Step-by-step explanation:
1. Write the function given:
[tex]f(x)=2x+1[/tex]
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:
[tex]f(2)=2*(2)+1[/tex]
Multypling numbers:
[tex]f(2)=4+1[/tex]
Adding the numbers:
[tex]f(2)=5[/tex]
Therefore the answer is B) 5
