Solutions

Chapter 2.5, Problem 38E
To determine

To graph: the function f(x)=x+43 using the graph of a standard function and then applying transformations.

Expert Solution

Explanation of Solution

Given information:

the function is f(x)=x+43

Graph:

Start with the standard function graph f(x)=x .

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

The table is thus obtained as:

    x 0149
    y 0123

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)=x is obtained as:

Now, the graph of f(x)=x+43 is the graph of f(x)=x shifted 4 unitleft, then 3 unit downwards.

The graphof f(x)=x+43 is obtained as:

Interpretation:

From the above graph it can be obtained that the graph of f(x)=x+43 is obtained by shifting the graph of f(x)=x

  4 unit left, then 3 unit downwards.
