Question

Do the following graphs represent a mathematical function? If not, explain why.

Answer 1

Yes

Explanation:

Whenever you are given a problem that's asking to see if a graph is a function or not, always use the vetical line test to determine that. In short, you draw a line accross each y axis point and if the line only goes accross one point throughout the graph then it's a function. Following the test we will see that both graphs are indeed functions.

Best of Luck!

Answer 2

• Yes for both

Explanation:

In such cases use the vertical line test. If the graph is intersected at more than one point, it is not a function.

Both the given graphs represent a function as both pass the vertical line test.
