Suppose the point (2, 4) is on the graph of y = f(x). find a point on the graph of the given function.

y = f(x + 1)

a) (1, 4)
b) (2, 5)
c) (3, 4)
d) (2, 3)

we are given the function y = f(x) in which the point (2,4) is present. This means the coordinate of the function y = f(x + 1) is still 4 while the x in the first function is added with one. Therefore, the answer to this problem is option C (3,5)
