Find the values of x for which the combined function h(x) = is undefined if f(x) = 5x + 1 and g(x) = x2 - 9.
x = 3
x = -3
x = ±3
x = ±9

The values of x for which the combined function h(x) is undefined if f(x) = 5x + 1 and g(x) = x² - 9 is ±3: Option C is correct.

Given the following functions;

f(x) = 5x + 1

g(x) = x² - 9

The combined function h(x) is expressed as

Substitute the given functions into the combined function as shown:

For the function to be undefined, the denominator will be equated to zero

(x + 3)(x - 3) = 0

x + 3 = 0 and x - 3 = 0

x = 3 and -3

Hence the values of x for which the combined function h(x) is undefined if f(x) = 5x + 1 and g(x) = x² - 9 is ±3

the answer is c. hope this !

step-by-step explanation:

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
