Answer 1

The possible values of for a, k, and b from the graph of the function will be D. a=4, k=2, b= pi/4.

What is a function?

A function simply means a relation between the set of inputs and the outputs.

A function from set X to set Y assigns each element of X to Y. In this case, the set X is the domain while the set Y is the codomain.

From the graph attached, it can be seen that the values of for a, k, and b from the graph of the function will be a=4, k=2, b= pi/4.
