Question

Integral of the constant function f(x) = k is:
C
0
kx+C
k+C

Answer 1

Refer to the attached image.

Answer 2

The integral of the constant function f(x) = k is: kx + C. This is because when you integrate a constant function, you are essentially finding the area under the graph. In this case, the area of the graph is equal to the value of k multiplied by the width of the graph (x) plus a constant.
