Question

The quadratic function f(x) is defined by the points in the table shown below.


The function g(x) is defined by the equation g(x) = (x−2)2+4.


Let a = the value of the y-intercept of f(x).

Let b = the value of the y-intercept of g(x).


b − a = _____

anonymous · Answer

The y-intercept is the y-coordinate corresponding to the x-coordinate 0. So, for g(x) substitute 0 for x and calculate g(x). That will give you b. From the table of values, find the y-coordinate corresponding to an x-coordinate of 0. That will be a. Then calculate b-a
