Answer

The graph of the polynomial function fx=x4-7x2+x+5 is shown below.


1Step 1. Write down the given information.

The given polynomial function is fx=x4-7x2+x+5

2Step 2. Construct the table of values.

Construct the table of values for different x and y for the function fx=x4-7x2+x+5.

3Step 3. Sketch the graph of the function.

The graph of the function fx=x4-7x2+x+5 can be constructed by plotting the ordered pair of x,y from the table.


4Step 4. Interpretation the graph of the function.

From the graph it can be interpreted that the graph cuts x-axis at four points. Hence it will have four real solutions.
