Find the values of x for which the combined function h(x) =f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.

For x = 3 or x = -3 h(x) =f(x)/g(x) is undefined.

Step-by-step explanation:

Given  : h(x) =f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x² - 9.

TO find : Find the values of x for which the combined function h(x) =f(x)/g(x) is undefined .

Solution : We have given that

f(x) = 5x + 1 and g(x) = x² - 9.

Function is undefined when denominator  of fraction is zero .

In h(x) =f(x)/g(x)

Here , g(x)  is the denominator then g(x) =0

x² - 9 = 0

On adding by 9 both sides

x² - 9 + 9 = +9.

x² = 9

Taking square root both sides

x =

x = ± 3

x = 3 , x = -3

Therefore, For x = 3 or x = -3 h(x) =f(x)/g(x) is undefined.
