Question

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k

Answer 1

Explanation:

k is the y-intercept. In other words, the y-intercept is the point ON the y-axis where the line goes through. Our line goes through the y-axis at 3. So, k = 3. The k value for f(x) is -2, right where the line goes through the y-axis. It will always be that way for lines.
