Question

In Exercises 77–92, use the graph to determine a.the x-intercepts, if any; b. the y-intercept, if any; and e. the missing function values, indicated by question marks, below each graph.

Graph showing x-intercepts at (0,0) and (5,0), y-intercept at (0,7).

Accepted Answer

Hello, everyone. In this video, we're going to be looking at this practice problem which states find the X intercept and the Y intercept of the function using the graph below. And in this graph, you can see that there's two dotted lines, one at Y equals seven and another at x equals five. And there's Two points that seem to be pointed out the point where those two dotted lines intersect, which would be five seven and the origin, which is where the line starts. So if we think about finding the X intercept and the Y intercept on this graph recall that the X intercept is where the function crosses the X axis and the Y intercept is where the function crosses the Y axis, the Y axis is the one that runs up and down. And the X axis is the one that runs from side to side. So if we look at our function which starts at the origin 00, you can see that it makes most sense for the function to cross the X axis at the origin point or where X equals zero. And you can see that it also crosses the Y axis at that same point or where Y equals zero. So that means our X intercept is equal to zero and our Y intercept is also equal to zero. So this becomes my final answer for this practice problem. And if we look at the answer choices, you can see that answer choice. A also has the X intercept at zero and the Y intercept at zero. So hopefully this video helped and see you next time.
