a function is shown: $f(x)=\frac{7}{2}x - 6$. what is the value of $f(4)$?

Explanation:

Step1: Substitute x = 4

Substitute (x = 4) into (f(x)=\frac{7}{2}x - 6). [f(4)=\frac{7}{2}\times4-6]

Step2: Calculate multiplication

First, calculate (\frac{7}{2}\times4). (\frac{7}{2}\times4 = 7\times2=14) So (f(4)=14 - 6)

Step3: Calculate subtraction

Calculate (14-6). (f(4)=8)

Answer:

8
