k=-3

Step-By-Step Explanation:

From graph, there is one local maxima and one local minima

will have two real solutions

We have to chose k such that f(x)=k have three real solutions

For f(x) to have 3 solutions, the last co efficient −2.75 needs to be positive and for that k must be equal to −3
