The y-intercept of a function is the point where the graph crosses the y-axis. To find the y-intercept of the function f(x) = -2x + 1, you need to set x = 0 and solve for y.
1. Substitute x = 0 into the function:
f(0) = -2(0) + 1
f(0) = 1
2. Therefore, the y-intercept of the function f(x) = -2x + 1 is at the point (0, 1).
So, the correct answer is O (0).
