Question

Using the function f(x)=3x-2
fill in the blank for F(5)​

Answer 1

f(5)=13

Explanation:

Lets fill in the variable first. If f=5, then we need to replace all of the 'x' with 5. So, our new equation is going to be f(5)= 3(5)-2. All thats left is some simple multiplication and subtraction. 3 times 5= 15 ; 15-2= 13.

f(5)= 13
