First, you would have to plug 3 into the equation
15-(3)/9-(3)
Then do the math
12/6
This can be simplified, since 12 and 6 are divisible by 6, which is their greatest common factor
2/1
So the answer is D. 2

Hope this helps!

What is the value of f(3) when f(x) = 4x + 1

valentina_108 [34]

Here is the equation:

$f(x)=4x+1$

You need to find f(3). To do that, substitute all the x's with 3:

$f(x)=4x+1 \rightarrow f(3)=4\times3 + 1$

The first thing you need to do is multiply 4 by 3. Multiply:

$4 \times 3 = 12$

Here is your new equation:

$f(3)=12+1$

To get your answer, you need to add 12 and 1. Add:

$12+1 = 13$

That means:

$\bf f(3)=13$
