Question

Given that g(x) = f(x) + k, enter the value of k for the functions f and g shown on the graph. Round to the nearest integer.

Two parallel diagonal lines graphed on a coordinate plane. Line f has y intercept 1 and line g has y intercept negative 1.

Answer 1

k = -2

Explanation: g(0) = f(0) + k. With f(0) = 1 and g(0) = −1, we have −1 = 1 + k, so k = −2.
