Why does the problem of finding the zeros (i.e. the inputs where a function assumes the value zero) receive such disproportionat
e attention in algebra?A. Because the problem of finding where a function f assumes the value c, i.e. solving f(x) = c, is equivalent to finding where the function f(x)-c assumes the value zero; and c = O is the only number for which f(x) = c can be solved by factoring f(x). B. It's because usually you want to know where a function crosses the x-axis. Crossing a different axis parallel to that is just not that interesting. C. It's because knowing the zeros allows you to determine the end behavior of the function, and the vertical and horizontal asymptotes. D. Because O is the lowest value (i.e. the minimum) that a function can assume. In many math applications, we need to know the minimum value of a quantity.
Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?
(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.
The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.
The simplest form of the function is f(x) = x2. The graph is a parabola often called the basic parabola. Notice that the graph is symmetrical about the y- axis. The y- axis is called the axis of symmetry of this function
