Question

given f(x)=1/3x + 7, evaluate the following: f(3)= f(x)=12

Explanation:

Step1: Substitute x = 3 into function

Substitute \(x = 3\) into \(f(x)=\frac{1}{3}x + 7\).
\[f(3)=\frac{1}{3}\times3+7\]

Step2: Calculate the first - term value

\(\frac{1}{3}\times3 = 1\), so \(f(3)=1 + 7\).

Step3: Calculate the final result

\(1+7=8\)

Answer:

8
