Answer:
Here is the equation:
f(x)=4x+1f(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 + 1f(x)=4x+1→f(3)=4×3+1
The first thing you need to do is multiply 4 by 3. Multiply:
4 \times 3 = 124×3=12
Here is your new equation:
f(3)=12+1f(3)=12+1
To get your answer, you need to add 12 and 1. Add:
12+1 = 1312+1=13
That means:
\bf f(3)=13f(3)=13
Step-by-step explanation:
13 is the ans
