Question

When f(x) is replaced with
f(x)+k, the graph that results is shown below
K=__?

Answer 1

k = 6

Explanation:

Parent function of the given graph → f(x) = (x - 1)²

If the parent function is shifted 6 units up.

Equation of the translated function will be → g(x) = (x - 1)² + 6

g(x) = f(x) + 6

Therefore, k = 6 will be the answer.
