Question

a(c) = 2c - 4
evaluate a(4)
type answer here.

Explanation:

Step1: Substitute c = 4 into the function

To evaluate \( a(4) \) for the function \( a(c)=2c - 4 \), we substitute \( c = 4 \) into the expression. So we get \( a(4)=2\times4 - 4 \).

Step2: Simplify the expression

First, calculate \( 2\times4 = 8 \). Then, subtract 4 from 8: \( 8 - 4 = 4 \).

Answer:

4
