Question

11 if f(x) = 7(x - 1) + 8, what is the value of f(1) ?

Explanation:

Step1: Substitute \( x = 1 \) into \( f(x) \)

Substitute \( x = 1 \) into the function \( f(x)=7(x - 1)+8 \), we get \( f(1)=7(1 - 1)+8 \).

Step2: Simplify the expression

First, calculate the value inside the parentheses: \( 1-1 = 0 \). Then the expression becomes \( 7\times0 + 8 \). Since \( 7\times0=0 \), then \( 0 + 8=8 \).

Answer:

\( 8 \)
