Question

The graphs of functions f(x) and g(x) = f(x) + k are shown below:

What is the value of k?

Answer 1

k = 4

Explanation:

k is the difference of y-intercepts (where the lines intersect with the y-axis). So, subtract the y-intercept of f(x) from the y-intercept of g(x).

2 - (-2) = 4

Hope that helps! :D
