To determine

## To graph: the function f(x)=14x2 using the graph of a standard function and then applying transformations.

Expert Solution

### Explanation of Solution

Given information:

the function is f(x)=14x2

Graph:

To plot the graph of f(x)=x2 ,use the plotting points method, substitute different value of x on f(x)=x2 to determine corresponding value of f(x) .

The table is thus obtained as:

 x -3 -2 -1 1 2 3 y 9 4 1 1 4 9

now plot each point of x along the horizontal axis and the corresponding value of f(x)=y along vertical axis and connect each point to form a smooth curve.

The graph of f(x)=x2 is obtained as:

Now, the graph of f(x)=14x2 is the graph of f(x)=x2 shrinking vertically by a factor of 14 .

The graphof f(x)=14x2 is obtained as:

Interpretation:

From the above graph it can be obtained that the graph of f(x)=14x2 is obtained by shrinkingthe graph of f(x)=x2 vertically by a factor of 14 .
