WebAs we can see in the above image, the graph of the function cuts the x-axis at two points x = -2 and x = 2. So, the zeros of the function y = x 2 - 4 are -2 and 2 as the x-intercepts of the function are -2 and 2. Hence, to find the zeros of a function using a graph, we determine its x-intercepts. Important Notes on Zeros of a Function WebNov 25, 2024 · Suppose we have to find the range of the function f(x)=x+2. We can find the range of a function by using the following steps: #1. First label the function as y=f(x) y=x+2 #2. Express x as a function of y. Here x=y-2 #3. Find all possible values of y for which f(y) is defined. See that x=y-2 is defined for all real values of y. #4. greatest sports photos
