Question
Select the correct answer.The y-intercept of a parabola is 1, and its vertex is at (1,0). What function does the graph represent?
Solution
The function that the graph represents is f(x) = (x-1)^2 + 1.
Here's the step-by-step explanation:
-
The vertex form of a parabola is given by f(x) = a(x-h)^2 + k, where (h,k) is the vertex of the parabola.
-
Given that the vertex is at (1,0), we can substitute h = 1 and k = 0 into the vertex form, giving us f(x) = a(x-1)^2.
-
The y-intercept of a graph is the point where the graph crosses the y-axis. This happens when x = 0. Given that the y-intercept is 1, we can set x = 0 in our function and solve for a: 1 = a(0-1)^2 = a, so a = 1.
-
Substituting a = 1 back into our function gives us the final function: f(x) = (x-1)^2 + 1.
