# In 27 and 28, functions f and g are defined. In each case sketch the graphs of f and 2g on the same set of axes and find a number x 0 so that f ( x ) ≤ 2 g ( x ) for all x > x 0 . You can find an exact value for x 0 by solving a quadratic equation, or you can find an approximate value for x 0 by using a graphing calculator or computer. 27. f x = x 2 + 10 x + 11 and g ( x ) = x 2 for each real number

To determine

To show:

Determine the approximate value.

f(x)=x2+10x+11 and g(x)=x2 for all real numbers x0.

Explanation

Given information:

f(x)=x2+10x+11 and g(x)=x2 for all real numbers x0.

Concept used:

Draw the graph of f and 2g on the same set of  axes.

Calculation:

Consider the functions.

f(x)=x2+10x+11 and g(x)=x2

For all real numbers x0.

Objective is to draw the graphs of 2 and 2g on the same set of axes.

Objective is to find an exact value for x0 by solving a quadratic equation
