Relate a vertical line test to understanding functions.
a.
each horizontal line drawn through the graph will intersect a function in only one location
c.
each vertical line drawn through the graph will intersect a relation in only one location
b.
each vertical line drawn through the graph will intersect a function in many locations
d.
each vertical line drawn through the graph will intersect a function in only one location

A

Step-by-step explanation:

You can automatically cross out A because it's a vertical line test.

The correct answer is A, because no output value can have the same input value as another.

Option d

Step-by-step explanation:

A function is a mapping or relation from a set A to set B with condition that each element in A has a unique image in B.

Also a function is invertible and hence one to one and onto.

Thus for any point in the curve there will be only one preimage as domain and also for a point in the x axis there will be one image as y.

This can be tested using a vertical line at any point of the domain of the graph.  If every point in the domain has the quality that a vertical line through it cuts the curve only one point means it is a function.

Hence we get

d.

Each vertical line drawn through the graph will intersect a function in only one location

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
