Question

in the function rule, y = 4x - 7, what is y when x = 3? y = ?

Explanation:

Step1: Substitute x = 3 into the function

We have the function \( y = 4x - 7 \). Substitute \( x = 3 \) into it, so we get \( y = 4\times3 - 7 \).

Step2: Calculate the value

First, calculate \( 4\times3 = 12 \), then subtract 7 from 12: \( 12 - 7 = 5 \).
