Question

F(x)=5x+1, find f(3a-4)

Answer 1

The problem is about functions, specifically, replacing a given value.

The expression f(3a - 4) indicates that x = 3a - 4, so we need to replace the variable with this expression.

`f(x)=5x+1\rightarrow5(3a-4)+1`

As you can see, we changed the variable for the given expression. Now, we use the distributive property

`f(3a-4)=15a-20+1`

At last, we reduce like terms

`f(3a-4)=15a-19`

Therefore, the answer is 15a - 19.
